The Benefits of the Box Strap

The Box Strap, an innovative metal bracket, is a game-changer in the industry. It’s designed to support double or single metal back boxes within stud walls, offering a better alternative to telescopic brackets and drylining back boxes. The Box Strap ensures the electrical boxes stay in place, even during the most challenging construction stages.

What are the main benefits of the Box Strap?

The Box Strap offers a wide range of benefits, such as providing a seamless finish when installing metal back boxes, reinforced corners, and precise dimensions for fixing points. Plus, pull tests from both the front and back of the bracket have confirmed its suitability for all types of installations on single- and double-layer plasterboard.

When examining different parties, this product is particularly beneficial for electrical contractors, drylining contractors, and property developers.

Electrical contractors

The Box Strap removes unwanted earth parallel paths during initial verification testing and ensures a flush finish with metal back boxes. The product also allows for installing metal boxes even after both sides of the wall are boarded, making the installation process smoother, faster, and more cost-effective than traditional approaches.

The bracket is designed for a 35mm metal back box with a 26mm depth, which allows for plasterboard thicknesses of 12.5mm or 15mm. This gives a total depth of 38.5mm or 41mm—sufficient for kitchen grids, media plates, and dimmer switches.

Drylining contractors

For drylining contractors, the Box Strap helps build baffle boxes without clashes, ensures walls can be closed without needing to cut around back boxes, and reduces any required rework.

Property developers

A significant benefit for property developers is the contribution to sustainability. It is estimated to help save up to 2,843kg of CO₂ across 200 apartments, helping reduce their carbon footprint.

Comparing the Box Strap to traditional methods

The many benefits of the Box Strap make it a respectable alternative to traditional telescopic bracket installation methods. This approach to installation often causes small bows on finished walls, clashes with baffle box details, and gaps between the back box and the finished wall.

This is due to the problems dryliners face when cutting around multiple boxes, particularly on party walls with two layers of staggered plasterboard.

Also, drylining back boxes can prevent the electrical switch gear from achieving a flush finish, and their lugs can bend backwards over time, causing the socket to become loose.
