Tronic Twin PVC Mounting Box for Surface-Mounted Wiring Devices

Our review

This Tronic pattress box is a surface-mounting base for wiring devices, made from PVC and sized to take two devices side by side. It exists for the situations where burying cable and back boxes inside the wall is not possible or not wanted, so the wiring and accessories sit on the face of the wall instead. That makes it a sensible choice for rented rooms, concrete or tiled walls, workshops, and retrofit jobs where chasing would create dust, damage and extra labour. Before ordering, confirm the box takes the device size you plan to fit and that a surface look suits the room. Compare with single boxes if you only need one device, and with metal-clad alternatives where impact resistance matters more than cost.
