Walton- Concealed Box – WPCB1G

Why Should You Order & FAQ

Using cheap metal or low-grade recycled plastic back boxes inside concrete walls introduces severe long-term risks. Metal concealed boxes quickly corrode from wall dampness and risk conducting electricity if a live wire touches the casing, while flimsy plastic boxes crack under masonry pressure and lose screw thread alignment over time. The Walton WPCB1G Concealed Box delivers an engineered, uncompromising safety solution. Formulated from high-grade, non-conductive polymer material, it provides absolute dielectric safety and withstands heavy masonry pressure without cracking. Its precise 60.3 mm nut hole pitch and 52 mm deep wiring cavity make installing modern switches fast and hassle-free, while leak-free conduit joining capabilities protect internal wiring from moisture ingress. Choosing genuine Walton concealed installation accessories ensures lifetime wall safety and structural reliability for your property.

Frequently Asked Questions (FAQ):

What type of switch and socket plates fit the Walton WPCB1G?
The WPCB1G features a standard 86×86 mm outer profile with a 60.3 mm nut hole center-to-center distance, making it universally compatible with all standard 1-gang modular switch plates, wall sockets, and fan dimmers.

How are electrical conduits attached to this concealed box?
The box features pre-molded knockout entries designed for easy connection using standard PVC solvent cement for permanent bonding or threaded conduit adapters for a tight, secure, and leak-free joint.

Why is non-conductive polymer better than traditional metal back boxes?
Non-conductive polymer never rusts or corrodes when embedded in wet concrete. Crucially, it acts as an electrical insulator, eliminating the risk of electric shocks or short circuits caused by loose live wires touching a metal box frame.

Is the 52 mm depth sufficient for modern modular sockets?
Yes. The generous 52 mm depth provides excess wiring clearance, allowing electricians to neatly fold incoming and outgoing conductors without crowding or bending terminals tightly behind the switch faceplate.
