This is a product we have developed to help combat the new 18th Edition Regulations that have come out in the electrical industry. With the fatal loses of a number of firemen who have lost their lives battling property fires and have been caught within cables that have fallen over the exit routs of buildings it is now a legal requirement to support cables above exit/entry points with a none melting material such as metal to prevent them from falling when exposed to heat or fire.

Regulations taking from BS 7671:2018

521.10.202 Wiring systems shall be supported such that they will not be liable to premature collapse in the eventof a fire.

NOTE 1: Wiring systems hanging across access or egress routes may hinder evacuation and firefighting activities.

NOTE 2: Cables installed in or on steel cable containment systems are deemed to meet the requirements of this regulation.

NOTE 3: This regulation precludes, for example, the use of non-metallic cable clips or cable ties as the sole means of support where cables are clipped direct to exposed surfaces or suspended under cable tray, and the use of non-metallic cable trunking as the sole means of support of the cables therein.

NOTE 4: Suitably spaced steel or copper clips, saddles or ties are examples that will meet the requirements of this regulation.

THE DESIGN

The Collar has been specially designed to restrict the screw head from being completely inserted into the desired location but verifying a secure fixture to support small/medium sized items.

The dominant end of the strap has been created to be installed by wrapping it around the item in question and securely connected into place by passing the exposed screw head through the aperture, to give a secure support for any item that is within the loop. The diameter of the aperture is smaller than the external circumference of the screw head. This is to give an extra level of security while supporting the cables.

The loop can be broken while leaving the collared end securely fixed in place, which will allow for extra cables to be installed with ease.

After the new cable is installed, the dominant end of the strap can be re-connected by passing the aperture over the screw head. The process can be re-applied as many times as required throughout the installation process.

A metal insert has been inserted within the plastic strap. This is to prevent cables falling in the case of a fire or extreme heat.  

In a fire scenario the plastic strap which is supporting the cables will melt and dissipate but the metal insert within the strap, which is securely connected over the screw head, will be left to support the cables safely. This will allow emergency services to enter and exit the premises in a safe and adequate manner
