When the device is new wiring or replacement a quick and cheap method of installation – open strip on the surface of walls or ceilings. And the popularity of this method is not reduced with the advent of high-quality ways of furnish of premises, cable lines are hidden in overhead or suspended ceilings, under a covering gipsokartonnymi sheets. Low cost open transaction due to the lack of additional cabling structures – trays, boxes, cables.

Open cabling

The method of laying a direct cable attached to the walls appeared at the dawn of electricity and has since remained virtually unchanged. The clamp, clip or mounting bracket separate the mounting element fixed on the supporting structure and fixed wire. This was used with various fasteners, depending on wall material, ranging from simple nail and ending with the anchor. For ordinary brick or concrete surface, the whole process consists of the following operations:

  1. Drilling holes in the wall or overlapping.
  2. To install plastic anchors.
  3. Fixing the cable in the mounting bracket.
  4. Mount by screws mounting brackets to the wall.

And although the process is quite simple, the use of anchor-clamps allows you to speed it up and simplify.

Dowel-clamp for fixing the cable is a plastic part combining functions of a fixture and the clamp holding the cable. Applying this fastener, there is no need to score the dowel, locking cable and attach the clamp. All actions are performed in a single step.

Types of anchor plugs

By design, this fastener is divided into:

  • Staples.
  • Spacer dowel clamp.
  • Plug for a clamp.

Mount cable type "clip"

Clip – the simplest form of the fastener. A narrow strip of plastic with a width of 6-8 mm – that is a dowel-clamp for fastening cable. The size of such a fastener should match the diameter of the cable. At the ends of the staples are made conical heterogeneity (teeth) to firmly grip the bracket into the wall opening.

Dowel-clamp for fastening cable when laying exposed

The cable mount is performed in two steps:

  • In the wall or the ceiling previously that a hole is drilled.
  • The bracket is put on the cable and inserted into the hole until it stops.

The step of fastening the cable of the product is determined by the strength of the base and a weight fixed to the cable. Typically, braces are made of polyethylene or nylon. Color scheme of these products: white, black or gray. Fasteners of this type are made for cables with diameter from 6 to 25mm. In addition to cables can assign bundles of cables, corrugated or smooth tube of appropriate diameter. When routing bundles of cables should consider the type of insulation, it must allow for the possibility of group gaskets.

A variety of such products – dowel-clamp for fixing a flat cable. This fixture features a flat loop form clamps adapted to set the same flat cable. You should consider the width and height of loop holes.

Spacer Clamp

This fixture combines in a single product plastic embedded parts, push rod and yoke. The installation is as follows:

  • In the wall of the drilled hole in accordance with the diameter of the dowel (usually 6mm).
  • The dowel-cable clamp, consisting of two halves, is inserted into the hole.
  • Between the halves of the dowel, a spacer rod is inserted and clogged with a hammer, breaking the dowel.
  • The clamp covers the cable and is tightened.

It is important to note that the length of the clamp allows to fix not only the cable but also corrugated or smooth-walled pipe with a diameter of 32 mm. Permissible load on a structure 8 kg, enough to strip the bundle of power cables.

The variant of the one-piece execution of the dowel. In this embodiment, the dowel is hammered directly into the hole. It should be carefully so as not to damage the dowel-clamp for fastening cable. A photo of such a fastener is shown below.

Finally, the clamp of this design can be executed in the form of a rigid arc, designed for fastening cable or tube of a fixed diameter. For the parallel strip available plug clamp for fixing the cable with the two wires that allows to reduce the effort for drilling holes.

The mounting platform with clamp

The fastener is a nylon or polypropylene dowel, the head of which is made in the form of a loop of rectangular shape. Into the hole head is threaded with a nylon or plastic tie fixing the cable, cable bundle or a protective pipe. The installation of such products as follows:

  • In the wall or overlap, an opening is arranged in accordance with the diameter of the dowel.
  • In the hole is jammed the dowel-stand.
  • Through the hole in the head is threaded the clamp.
  • The cable product is fixed with a yoke.

This design allows you to apply not only plastic, but also metal clamps of the appropriate width.
