Tronic Twin Square Box Back Box for Flush Wall Wiring

Our review

The Tronic Twin Square Box is a back box for wiring equipment, designed to sit recessed behind the wall surface rather than on top of it. Its job is to hold and support the wiring accessories that mount into it, while giving high- and low-voltage cables a route through the wall cavity. That makes it most useful during a build, renovation, or any stage where walls are still open, and for anyone planning a wall-mounted TV or furniture that needs to sit flush. Before buying, confirm the box size and depth match your accessory and wall thickness, since no specifications are listed here. Compare with single boxes if you need fewer gangs, and with surface-mounted boxes if you cannot chase the wall.
