The box includes multiple moulded knockouts for cable entry from the top, bottom, sides and rear, and two brass fixing lugs for securing the faceplate.\u003c\/p\u003e\n\u003cp\u003eDesigned for residential, commercial and light industrial applications where surface wiring is the preferred or only option, the box suits solid walls where chasing out is impractical, surface-run conduit installations, workshops, garages and utility rooms. The 25mm depth accommodates standard switches and sockets without deep terminal blocks. The box mounts directly to the wall with screws through the rear base plate, or can be fixed to trunking or cable management systems.\u003c\/p\u003e\n\u003cp\u003eThe white finish blends with white walls and white faceplates for a low-profile appearance, though the box itself remains visible as a surface-mounted fitting. The moulded plastic construction is lightweight and resistant to impact, and the box carries BS EN60670-1 certification for use with standard UK electrical accessories rated up to 13A.\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is a surface box used for?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA surface box sits on the wall surface rather than being recessed into it, allowing electrical faceplates to be fitted where cutting into the wall is not possible or desirable.
