Centaur 1 Gang 32mm PVC Surface Back Box with 20mm Knockouts (White) (SB 7/20W)

The Centaur SB 7/20W 1-gang pattress box provides a durable solution for surface-mounting electrical accessories. At 32mm deep, it offers ample space for wiring, making it ideal for installing a wide range of switches and sockets where a flush-mounted box is not feasible.

Manufactured in the UK from high-impact resistant, self-extinguishing PVCu, this box is built for durability and safety. Its design is optimised for installers, featuring versatile cable entry options with knockouts on the sides and base to accommodate both mini trunking and a 20mm conduit.

The box features fixed lugs for secure accessory fixing and elegant round corners for a clean, modern finish. It is fully compliant with BS 4662, ensuring a reliable installation for any professional electrical or fire alarm application.
