Remember old houses? More precisely the walls. Hanging wiring, which not only does not look aesthetically pleasing, but is also a hindrance when different types repair. For example, to re-glue wallpaper, you have to constantly trim it and insert wires and fasteners. Nowadays, exposed wiring can not only be beautifully laid out in boxes, but also generally hidden using various types of cable laying structures.
Cable channel for wires: types and differences
IN various rooms, electrical wiring is often carried out in a cable channel. Today, the market offers a huge number of types of boxes in which current-carrying conductors are laid.
Electrical mounting box types:
- Floor;
- Parapet;
- Skirting;
- Flexible;
- Wire;
- Staircase.
Cable channels floor type, easy to use. They are made of a flat base with sides and a semicircular lid, which will allow you not to cling to the box when moving.
In order to hide wiring from an air conditioner or other office equipment, parapet boxes are used. Installed mainly in office and administrative buildings.
Plinth box (decorative), used in apartments and private houses. Most often used for laying additional electrical wiring lines. In order to lay conductors along uneven surface, use a flexible (perforated) cable channel. Thanks to its features, it is very convenient to use. The most simple view The cable channel is wire. Manufactured by welding wires into trays of a certain length. It is used for laying cables and wires in technical or common areas (panel rooms, underground parking lots).
The main materials for making boxes are plastic or metal. It all depends on the design and purpose of the product.
To lay more massive cables, ladder cable channels are used. They are made in the form of metal channels fastened together.
There are cable channels various shapes and sizes. For example, to lay one wire of small cross-section, use a box Not large sizes. To lay the LED strip, cable channels with a transparent cover are used.
How to properly attach a cable duct to a wall
Provided that installing hidden wiring is not possible, an excellent alternative is to install wires in boxes. But in order to properly secure the box and subsequently lay the wire in it, it is necessary to rely on some installation rules.
Methods for attaching the cable channel:
- Using glue;
- Using dowels.
Gluing a wall box is not a very common method. This is due to the fact that if the walls are not level, the box will be glued unevenly and there will be gaps between its base and the wall, which do not look very aesthetically pleasing. But if it is impossible to fasten the box in any other way, this one is quite practical.
In order to attach a cable channel using glue, you must first clean the surfaces to be glued. The back side of the box is cleaned of various contaminants using a rag or cloth. Then the wall surface is cleaned. There should be no dust on it, the surface should be dry.
Apply glue to the back of the box. It should be applied in a wavy line, the edges of which do not approach the edge of the box by more than 5 mm. Then the base of the box is pressed tightly against the wall and maintained in this position for some time. It all depends on the type of glue.
The method of laying a box using glue is suitable, for example, for attaching to drywall or if the wall cladding material is stenolite.
Regardless of the type of box (metal or plastic), the most reliable way is fastening with dowels. This type relevant for fastening the box to concrete or brick wall.
Installation of the box is carried out after drilling the wall with a hammer drill. Plastic dowels are inserted into the finished holes, a cable channel is attached to the wall, which is screwed with self-tapping screws.
Do-it-yourself installation of electrical wiring in cable ducts
In Soviet times, in any apartment, wiring was laid openly. And from an aesthetic point of view, this method not very remarkable. But there is an opportunity to fix everything by hiding the wires in boxes, which not only look better than open wires, but also ensure safety of use.
List of works step by step:
- Planning;
- Marking the walls;
- Preparation of structural elements;
- Installation.
First of all, for any type of electrical installation work, a clear plan is drawn up, according to which the wiring will be located and all structural elements (sockets and switches) will be connected.
Since markings are usually applied to the walls after finishing, try to do this work carefully.
After this, the structural elements are prepared. The box is cut to the required length (it should be cut carefully so as not to damage the box). In order to connect the cable channel at the corners of the room, at an angle of 45 0, the corners are cut off in the places where the connection will be made.
In order to install a cable channel, holes are drilled in the walls (the step between the holes is from 50 to 60 cm), such a distance will allow you to tightly press the entire surface of the cable channel with self-tapping screws. When connecting the box to sockets and switches, leave a small margin, which can then be cut off.
IN drilled holes dowels are inserted and the box is screwed with self-tapping screws. Make sure that when tightening the screw does not deform the box. It is worth noting that before tightening the self-tapping screw, for ease of wiring installation, a thin wire is wound onto its head, which secures the cable. At the end of the work, the conductors are laid and connected.
Flexible cable channel: DIY production
For self-made this product, you do not need any special skills or equipment. Manufacturing is carried out using available tools and materials.
To work you will need:
- Metal racks for drywall;
- Self-tapping screws or rivets;
- Metal scissors;
- Screwdriver.
Before making a flexible box, you need to decide on its length. After that, metal stand cut into small pieces of approximately 10 cm. The number of pieces depends on the required length of the product.
After this, to give mobility, each workpiece must be given a certain shape. From four sides, two sides of the blanks, using metal scissors, ears are cut out, the length of which is approximately 2.5 - 3 cm. This will allow the component elements not to cling to each other with the sides when the structure is deformed.
In order to ensure the laying of wires, each part after work should be processed with a grinder.
To install rivets, you need to use a screwdriver with a drill to make holes in the ears. The diameter of the holes must correspond to the diameter of the rivets. Next, using a riveting tool, the rivets are mounted.
After completing the assembly of the structure, in individual elements, several holes are made through which the wires are fixed to the body of the product. It is better to make holes with inside constituent elements. For ease of drilling, the structure is laid on a wooden lining with its flat side. Ready!
Do-it-yourself cable channel installation (video)
Using this information, you can easily not only choose the type of cable channel that suits you, but also install it correctly. Which is undoubtedly beneficial from an economic point of view.
In production, technical and administrative premises, do hidden wiring in an array of fences is expensive, and sometimes technically infeasible. There is only one way out - to arrange external gasket electrical communications over walls and ceilings. Electrical installation rules (PUE) prohibit open installation of cables indoors. This applies to the internal spaces of buildings and structures with increased level humidity. Electrical boxes decide this problem. The article covers the topic of how to attach a cable channel to a wall.
Why do you need a cable channel?
Otherwise, the product is called an electrical box. Its main function is to provide protection for cables and wires from external negative influences. The aesthetic side of the issue is important, because it is not very pleasant to see a chaotic accumulation of wires and cables on the walls of the room.
Installation of cable channels groups wire communications according to their purpose. The power cable is laid in one channel, and low-current wires are placed in the other. Multi-channel boxes can carry conductors to the distribution node. Then single-channel or double-channel boxes are led out from the node in the required directions.
Advantages of cable channels
The generally accepted name for communications laid in boxes is exposed wiring, which is not true. It is better to call such a system closed external electrical wiring.
Closed external electrical wiring has a number of advantages:
- ease of installation of cable channels;
- styling various types communications in large quantities;
- inexpensive and fast communication to consumers;
- wide selection of product sizes and colors;
- unobstructed access to wiring along the length of communications.
Types of cable channels
Industry building materials produces a wide range of cable channels. Among them, 7 types of structures should be noted:
- rigid wall PVC boxes;
- soft vinyl cable channels;
- galvanized steel and aluminum boxes;
- corrugation;
- floor channels - baseboards;
- ceiling cornices - fillets;
- movable chain cable channels.
Rigid type PVC wall boxes
These are popular designs. The longitudinal edges of the box and the lid with grooves and projections form a locking system. After laying the cables and wires, the channel is snapped into place with the outer panel.
PVC boxes are produced with both one-sided and double-sided snap panels. The two-way system is much more reliable. Cable channels are sold in the form of two-meter strips. They offer to purchase corner fittings for them. These are parts that cover the internal and external corners of the cable route.
To lay the cable channel route, you will need the following tools and materials:
- Ruler and tape measure;
- Marker or pencil;
- Laser level;
- Hammer;
- Hammer;
- Hacksaw or angle saw with saw blade;
- Cable channels;
- Corner fittings;
- Dowels.
Installation of PVC boxes
Installation of PVC cable channels occurs in stages. The actions are performed sequentially:
- Mark the cable route on the walls using a pencil, ruler and tape measure;
- The laser level controls the horizon and vertical markings;
- Using a saw or miter machine, cut the strips of boxes into the required installation sections;
- Applying a section of the box along the marking line, drill holes in the wall with a hammer drill through the plastic. The holes are made at a distance of 300-400 mm from each other, depending on the massiveness of the wiring. At corners of turns, the distances between nearest holes are halved;
- Dowels are hammered into the holes to secure the channels to the concrete walls. Electrical wiring is placed in the box;
- The corners of turns are covered with fitting covers;
- The top panel is installed on the box, snapping the locks;
- Remove dust and dirt from the surface of protective structures.
Important! If you need to run a cable from a room to an adjacent room, then drill through the box through hole in the partition. On the side of the adjacent room, a cable channel is installed at the same height from the floor. The hole goes outside this channel. The cable is routed through the opening into the adjacent room.
Soft Vinyl Cable Channels
Boxes from this material began to be made relatively recently. Thanks to its flexibility, the box easily bends around internal and external corners.
Vinyl products do not require the installation of additional corner and other fittings. Fastening channels to the wall is done in the same way as installing rigid PVC products. The locking system is easy to fix and at the same time provides a strong connection between the box and the lid.
Cable channels made of flexible material are convenient to use not only in technical and utility rooms, but also in living rooms.
Galvanized steel and aluminum boxes
In their design, metal cable channels are not much different from PVC products. Metal is more durable and durable material than plastic.
Note! Electrical boxes made of metal are much more reliable, but also much more expensive. plastic products.
Corrugation
The cable channel is fastened to the corrugated wall using special clips. Holes are made according to the markings using a puncher. Through the mounting opening of the clip, a dowel is driven into the hole. The flexible hose is snapped into place with clip brackets. Corrugated pipes there are different diameters and can accommodate quite a large number of wires at the same time.
Special distribution boxes divide the wires into different directions, laid in other corrugated shells. Flexible cable channels are used in utility rooms, technical rooms and workshops.
Additional Information. The advantage of flexible boxes is that installing a corrugated cable channel allows you to replace one cable or several wires without disturbing the position of other communications.
Floor channels - skirting boards
At the end of the last century, universal designs of skirting boards appeared on sale. The internal space of plastic products began to be used as cable channels.
On sale you can find floor products of various colors and structures with internal channels for laying cables. Mostly inner space Floor cornices are used to place television or Internet cables.
The fastening systems for external panels-covers of skirting boards differ in the shape of the locks. This can be a completely removable strip between the vertical and horizontal shelves of the plinth, or a longitudinal U-shaped core in cross section can be removed.
To secure the baseboards, dowels are driven through the vertical shelf of the product into the wall. They are hammered into recesses pre-made with a hammer drill in the wall. At the internal and external corners of the plinth routes, special plastic corners. After laying the communications, the wires are covered with a longitudinal panel, snapping the locks.
Ceiling cornices - fillets
Ceiling cornices that cover the corners where the walls meet the ceiling are called fillets. Most often, the same skirting boards with internal channels are used as fillets. Fastening fillets is no different from installing floor cornices.
Along the perimeter of the ceiling in the walls they make a perforator mounting holes in increments of 300 mm. Hammering the dowels in with a hammer secures the fillets. After laying the communications, the ceiling boxes are covered with longitudinal panels-lids.
Movable chain cable channels
Recently, mobile cable channels have appeared. The products are used to protect wired communications connected to complex mechanisms, parts of which perform reciprocating movements.
The movement of a chain cable channel resembles the movement of the tracks of an all-terrain vehicle or a tank. The product is made of high-strength wear-resistant plastic. Each section traction chain You can open and check any section of communications.
The movement of the cable chain duct does not cause any noise. The shape of the traction chain sections is similar to the track track. The material of the products consists mainly of high-strength nylon, is flexible and can withstand high tensile loads.
Various home-grown designs of cable channels are known. Basically, they are quite primitive and may be far from safe. Products need to be purchased only from factory-made ones.

Masters with gray hairs remember how open wiring was done thirty years ago, they saw what changes took place in technology fifteen years ago and can compare with in modern ways styling open wiring. So that you have something to compare with and make decisions easier, we will make a brief overview of all existing and existing methods.
It’s called so beautifully now, but previously it was the only option for open wiring. It was used not only in the bathhouse, but also in residential premises. The wires were fixed on porcelain insulating rollers.
For such wiring electric wires should only be single-core, the cups are fixed at a distance of no more than ten centimeters, plus one at each turn. The wires had to be twisted, and this was a long and tedious task. In addition, white insulation became dusty and dirty within a short period of time, and people often settled in it. permanent place residence of various spider bugs.
Today, open wiring using the described method is installed only by great lovers of antiquity, who do not know what appearance it will have in a few years.
More good option, electrical cables were hidden in plastic pipes, which looked much better on the walls. In addition, plastic pipes served additional protection from mechanical damage.
Disadvantages: complexity of installation and routine maintenance. Electricians still remember how difficult it was to pull cables through pipes, especially if there were bends.
Often the pipes had to be cut and, after pulling the cables, connected with couplings. Another significant drawback is the great difficulty during production. repair work. Due to its low cost, open wiring in plastic pipes is still quite often used today.
Open wiring in cable channel
According to most professional electricians, the most the best option open wiring. Essentially, it can only be called open based on the cable laying technology; in appearance, it bears little resemblance to the usual options; rather, it can be called semi-open.
Manufacturers produce a huge number of options both in the number of cables and in the method of fixation, overall dimensions and the availability of additional accessories. The advantages include ease of installation, durability, safe operation, versatility of use, and the presence of numerous special additional accessories. Additional elements solve issues with internal and external corners, turns, connections of sockets, switches, mounting boxes, etc.
It is this type of open wiring that we will focus on in the article. Before directly considering the issues of fastening cable channels, you should learn a little about their types and technical capabilities.

Types and features of channels
Cable channels are classified according to several important criteria.
| Characteristic | Description | Illustration |
|---|---|---|
| By location. | They can be floor, parapet, baseboard and main. The appearance of each category is maximally adapted to the installation site; it can resemble profile moldings. | |
| According to color design. | There are light, dark and imitation natural wood. | |
| By linear dimensions. | Designed for one, two, three or more cables. External dimensions range from 40×25 mm to 100×60 mm. May have sharp or rounded corners and increased lid dimensions. There are options with high lids, their shelves cover internal elements the channel along the entire height - the impression of a monolithic product is created. This not only improves appearance electrical wiring, but also increases its protection from negative influence external factors. | |
| By the number of locks - with one or two locks. | Two locks more reliably keep the lid from opening spontaneously and eliminate the possibility of deformation of the lid. | |
| According to the material of manufacture. | Plastic, steel and aluminum. Aluminum plated plastic film under various breeds wood, go well with existing interiors, but in terms of price they are considered the most expensive option. Plastics do not support open combustion; the use of such channels for laying cables with voltages up to 1000 V is permitted. | |
| According to the degree of protection from dust and moisture. | Certain brands of plastic channels have a degree of protection IP55, which allows them to be used on open area and in rooms with high humidity levels, protects against multidirectional splashes of water. This is a very important characteristic for a bathhouse. |
Video - How to select and install a cable channel
The main parameters when choosing a cable channel are the cross-section and number of cables that are planned to be laid in the network. Of course, you need to pay attention to the appearance, try to choose an option that would harmonize as much as possible with existing interior bathhouse premises.
Stages of installing wiring in a cable channel
Step 1. Draw a plan for the placement of electrical networks, devices and equipment.
Consider several options, consider the possibility of increasing the power and number of electrical fittings. Depending on the maximum total power of all electrical energy consumers, select the cable diameter. To make your choice easier, refer to table No. 1.
Experienced electricians do not keep all the values in their heads, they only remember that 1 mm2 cross-section copper cable designed for 1.3 kW of power at a voltage of 220 V, and 1 mm2 of aluminum cable holds only 0.5 kW at the same voltage. The following is simple arithmetic. If a cross-section of 2.5 mm2 is indicated on the copper cable sheath, then it can be used to connect current consumers with a total power of 2.5 × 1.3 = 3.25 kV. Always round up and use this cable at 3.0 kW.
Practical advice. For a bath it is enough to buy an ordinary plastic box with dimensions of 40x25 mm, it easily accommodates a cable that can withstand power up to 10 kW. In the implementation there are boxes made under ceiling plinth or floor baseboard. Perfect solution, but it needs to be thought through before performing the finishing finishing works walls or floor. We recommend installing the central wiring above the floor and the terminals below. lighting, mounting boxes, sockets and switches should be made from below. But this is not for everyone; you can use other options for installing electrical wiring.
You should have it drawn as general circuit diagram electrical wiring starting from the introductory switchboard, and a separate diagram for each bathhouse room.
Select fastening hardware depending on the wall material. You need self-tapping screws for wood, special hardware for drywall, and dowels for brick.
Each manufacturer of cable channels produces a wide range of additional elements: internal and external corners, triangles, plugs, couplings, mounting boxes, sockets, switches, etc. Carefully calculate the nomenclature and total quantity, we recommend taking a few pieces in stock. They cost pennies, and in the end it will cost much less than going to the store again to purchase the missing elements.
Step 2. Make the markings. For example, we will take a bathhouse, the walls of which are already completely lined and flooring. There is only one option for open wiring in cable channels - on top of the walls. It is better to do the wiring near the floor; in this case, it is much easier to drill holes and attach the cable channel. Working near the ceiling with your arms outstretched all the time is tiring and inconvenient. Moreover, you will have to hold a rather heavy drill and screwdriver in your hands.
Experienced electricians make markings on the walls only for mounting boxes, switches and sockets; cable channels are installed immediately without applying preliminary lines. Take a section of the channel, place it against the wall, set a level on top (or side) and adjust the spatial position. Next, hold the box with one hand, and with the other hand, drill holes in the bottom for the hardware. This is quite difficult; you not only need to have experience, but also be able to optimally organize the installation process. We will tell you how to make detailed markup for beginners, this will help avoid annoying mistakes.

How to mark cable channels
You need to have a hydraulic level, a rope with blue, a ruler and a pencil.
Don’t be afraid to use blue – the broken lines will be covered with a cable duct. Start marking with distribution panel, while simultaneously taking into account not only the characteristics of the cables and the placement of sockets, mounting boxes, switches, etc., but also the layout and purpose of the premises.
The markings and calculations are completed, installation can begin.
Step 3. Fastening cable channels. Fastening methods depend on the material used to make the walls and the material of the finishing cladding. Let's consider each option in detail.
Prices per building level
construction level
Attaching cable ducts to plasterboards
Gypsum boards consist of two layers of paper with gypsum sandwiched between them. The material is relatively new and is very popular among professional construction companies- it is easy to work with, it is very technologically advanced, etc. But consumers cannot say so many good words about this material - the strength of plasterboard boards is below any criticism. Remove the paper from the drywall and it will crumble; any noticeable force on the drywall will not result in visible damage to the surface. Accordingly, attaching cable channels to such material is quite problematic. There is no point in using screws (even special ones). If you “overdo it” a little while screwing, the threads in the plaster will turn and the fastening strength will approach zero.
We recommend using only plastic cable channels on such walls; the use of aluminum ones is highly undesirable. You need to fasten the plastic with liquid nails; in the most critical places you can additionally use special screws.
Practical advice. Due to the fact that plasterboards have a decorative finishing coat, it needs to be checked for adhesion with liquid nails. Not all types of paints and not all types of wallpaper are suitable for gluing. First, glue a small piece of plastic box in some secluded place and check the strength of the adhesive every other day. Everything is fine - you can use this technology.
Apply liquid nails to the box with reverse side thin layer, the application strip should be wavy to increase the adhesion area. There should be just enough glue so that when pressing the cable channels it does not protrude beyond their perimeter. To increase the reliability of fastening, you can additionally fix it with self-tapping screws.
Attaching cable ducts to brick walls
A complex and time-consuming option, it is necessary to use dowels. The advantage of dowels is high reliability, but in our case no noticeable physical activity channels are not expected, the advantage becomes unnecessary, and large labor costs remain. How to attach cable channels to dowels?
- Place the cut channel blank in place of fixation, and use a metal drill to drill holes in the bottom at a distance of 15–20 centimeters. Drill the holes carefully; only the end of the drill should be drilled into the wall. In this way, marks for installing dowels on the channel and the wall are simultaneously made.
- Remove the channel, change the drill to a pobedit one, switch the drill from drilling mode to perforation mode. Use a pobedite drill to make holes for the dowels.
Important. Drill carefully, select the correct drill diameter. It should be a few tenths of millimeters smaller than the diameter of the plastic element of the dowel. This element should fit into the hole with little effort.
- Place the plastic cable channel in place, align the holes in it and the wall, insert the plastic elements of the dowels, hammer in the metal dowels.
If the wall is uneven, then choose places for drilling holes in convex areas, this way you will be able to avoid visible deformation of the cable channel. Making a mistake is not a problem. Most metal dowels have a thread; you can unscrew them a little, loosen the pressing force against the wall, and thereby correct the resulting deformation.
In all places where individual sections of cable ducts are cut or joined, additional connecting elements must be secured. This general rule for all methods of fixing cable channels.
Professional installers use a pneumatic gun and special nails to fix cable ducts to brick or concrete surfaces. But a pneumatic nail gun is expensive equipment; purchasing it for one bathhouse is impractical.

Attaching cable ducts to wooden walls
For baths - the most common option, fastening is done with self-tapping screws, the length of the screws is approximately 1.5÷2 centimeters. On a flat surface, you can first drill holes in the cable channel at a distance of up to twenty centimeters, and then use them for fixation. It's easier, but longer. If you have practice construction work, then the screws can be screwed into the bottom of the channel cable and the wall at the same time.
Problems may arise when laying exposed wiring along clapboard walls. The lining boards have a profile; screws should be fastened carefully. If the self-tapping screw hits a convex section of the profile, great, you can tighten it completely. If you have to screw a self-tapping screw into the concave part of the profile, do not tighten the self-tapping screw all the way, make sure that it does not disrupt the linearity of the plastic channel.
We have already advised buying special additional elements for passing external and internal corners, connections at right angles, tees, etc. All joints can be filed at right angles; the cut may not be perfectly smooth. Overlay elements will be closed problem areas, the connection will be beautiful, the work will speed up significantly. You can cut a plastic cable channel with a hacksaw, special mounting scissors, or a cylindrical grinder (grinder) with a metal disc.
What to do if for some reason there are no additional elements, how to cut the channel so that the connection is not noticeable?
First use standard long channels, do not rush to cut them into pieces. You should always have all the pieces at hand, among them you can choose the length you need and not touch the whole one. To do this, it will be necessary to move the socket a few centimeters in one direction or another - no big deal.
If you need to store purchased cable channels for a long time, then place them on flat plane, do not expose them to direct sun rays. Over time, all plastics, when exposed to sunlight, darken and lose their plasticity. Don’t believe manufacturers’ advertisements about “complete resistance” to UV rays thanks to modern technologies, various innovative additives do not completely protect plastic from such influences, but only slow down the process of physical aging.
Mounted cable channel
During the construction of a house, electrical wiring is installed in a hidden way, under the plaster. Complete replacement electrical wiring is usually done during overhaul. In this case, grooves are made in the wall, into which the wire is laid.
But what to do when there is no opportunity or desire to engage in dusty wall slitting? Or do you need to connect a recently installed powerful electrical appliance, such as a water heater? In this case, many choose open method laying of electrical wiring, and fastening to the wall is carried out using a cable channel.
Types of cable channels
Several criteria are used to classify a cable channel:
- Size. There are small products for laying one wire of a small cross-section or large boxes designed to mount up to eight conductors of different cross-sections on the wall;
- Material of manufacture. They produce aluminum, steel and plastic structures. For indoor installation, plastic models are more in demand, and fastening steel and aluminum boxes is more often used when laying electrical wiring along the facade of a house;
- Location. The cable channel can be fastened in several places. The design of the product is maximally adaptable depending on the installation location. There are plinth, parapet, main and floor models.
Note! By color design The cable channel most often has a neutral White color, suitable for any finish. Models that imitate a wooden structure are also popular.
Installation technology
To facilitate profile connection, use those offered by the manufacturer additional elements: T-shaped and corner structures, strip connectors, various bends and other accessories.
To install sockets and switches, it is best to use overhead versions of these products or use box models with built-in structures.
Today we will talk about how to attach a cable channel to the wall with your own hands. In fact, installing an electrical plastic box is not difficult at all. The main thing is to choose the right mounting method depending on what the walls in the house or apartment are like. Next we will look at everything existing options installation and will provide several important nuances that will allow you to properly secure the cable channel to the wall.
Method No. 1 - Self-tapping screws
If you decide to perform either an apartment with plasterboard partitions, then the installation of the cable channel must be done with special wood screws. The fastening step depends on what load will be placed on the plastic box, or more precisely, how many wires need to be stretched inside, and what their cross-section is. Typically, to securely secure the cable duct to wooden wall or plasterboard, it is enough to screw screws every 40-50 cm. If the walls are uneven, it is better to reduce the fastening step, this will hide all defects and gaps.
You should not choose screws that are too long to install the cable channel yourself. To securely fix the box in the wall, it will be enough to screw in fasteners about 40 mm long. For screwing, it is best to use a screwdriver with a Phillips bit. About that for home renovation, we talked about in the corresponding article!
Method No. 2 – Dowel-nails
If you need to attach a cable channel to a concrete or brick wall, which is a typical situation for an apartment or a house, you cannot do without dowel nails, also called “quick installation”. In addition, for fastening you will need a hammer drill with a 6 mm drill. So, in order to independently fix the electrical box for the cable on a wall made of concrete or brick, you need to perform the following steps:
- Pre-drill 6 mm holes in the bottom of the cable channel every 40-50 cm.
- Attach the box to the wall according to the markings (more on this later) and mark the drilling points that coincide with the finished holes in the cable channel.
- Drill holes according to the marks on the wall.
- Place the plastic box and drive the dowels into the appropriate places.
- Hammer the nails.
Using these simple instructions, you can install the cable duct yourself in a wall made of concrete or brick. We draw your attention to one very important point– do not drill holes with a drill while leaning the box against the wall. When drilling plastic, the impact mode can provoke the appearance of cracks, which will have a negative impact both from the visual side and from the durability of the finished wiring.
Detailed video instructions for installation work
Method No. 3 – “Screws with a press washer”
If there is a need to attach a cable duct to metal with a thickness of less than 2 mm or aluminum profile, then for fastening we advise you to use metal screws, also called “bugs”. By the way correct name bedbugs - self-tapping screws with a press washer. They do not require pre-drilling a hole. There is nothing complicated in installing an electrical box on metal surface no, the main thing is to choose good screws and load the screwdriver.
There is also a special gun with which you can independently attach the cable duct to concrete. Video provided detailed description installation:
We fasten the product with a gun
Method No. 4 – Liquid nails
Well, the last way to attach a cable channel in an apartment or house is with special glue “liquid nails”. The need to glue the cable channel to the wall arises if another installation option is not possible. Most often, liquid nails are used when installing electrical boxes on bathroom tiles or a smooth metal surface. However, it is unlikely that it will be possible to secure the box well with glue alone. Glue mixture more often used as additional option fixation. It can be combined with self-tapping screws or even quick installation.
There are very important nuance fastening the cable channel with glue - first you must apply the adhesive mixture to the surface of the box, and then lean it against the wall according to the markings. As soon as they leaned back wall to the wall, remove it and wait a few minutes for the glue to thicken a little on both surfaces to be glued. After the liquid nails “grab” at least a little, press the cable channel against the wall as hard as possible, the main thing is not to break it. Like this in a simple way You can attach the cable channel with glue yourself.
So, so that you can install the cable channel correctly and at the same time quickly, we recommend that you familiarize yourself with the following installation nuances:
