These back boxes are made from fully recycled and recyclable post-consumer plastic. They’re for plasterboard cavity walls, with tabs and a lip that grip the plasterboard securely. Unlike other plastic back boxes, we’ve designed them to work perfectly with our switches and sockets that sit flush to the wall. They’re deep enough to hold all the electrics inside, and the design means the switch or socket plates sit in the correct position every time.

A metal back box is a metal enclosure used to house electrical sockets, switches, and other electrical fittings. They are installed within walls and provide a secure and stable mounting for the electrical components.
Common sizes for metal back boxes in the UK include:
Yes, metal back boxes must be earthed to ensure electrical safety. They typically have an earth terminal to connect the earth wire from the electrical circuit.
Metal Back Boxes: More robust, provide better protection against fire, and are often required by building regulations for certain installations.
Plastic Back Boxes: Easier to install in drywall or plasterboard, non-conductive, and do not require earthing.
Knockouts are pre-scored sections on the back or sides of a metal back box that can be easily removed to allow for cable entry. They are designed to be punched out using a hammer and screwdriver or pliers.
