Description

The Knightsbridge 1 gang blanking plate covers unused or redundant single-gang electrical boxes behind a brushed chrome square-edge faceplate. The 89mm x 89mm plate is constructed from premium-grade steel with a directional brushed finish that minimises fingerprints and reflections, and includes an integrated earth terminal for safe installation.

Designed for both residential and commercial environments, the plate sits flush to the wall with a 10.5mm projection from the mounting box and requires a minimum 16mm back box depth. The built-in gasket seals the plate against the wall surface, preventing dust ingress behind the plate and giving a tight finish. The IP20 rating confirms it is suitable for dry indoor locations including living rooms, bedrooms, offices and hallways.

The brushed chrome finish shows fine horizontal grain lines across the steel surface, creating a cooler metallic tone than brass finishes and pairing well with contemporary, industrial and monochrome interiors. The square edge profile sits flush to the wall without a raised border, giving a clean transition between plate and wall surface. Knightsbridge backs this plate with a 25-year warranty.

Frequently Asked

When would I use a blanking plate?

Blanking plates cover electrical back boxes that are no longer in use, such as where a socket or switch has been removed during renovation or where a box was installed but never fitted. They provide a safe, finished appearance and prevent access to the wiring behind the wall.

What back box depth is required?

The plate requires a minimum 16mm back box depth. Standard UK single-gang back boxes are typically 25mm or 35mm deep, so most installations will accommodate this plate comfortably.

Does the plate include fixings?

The plate includes an earth terminal for safe connection to the back box earth. Mounting screws are typically supplied with the back box itself; if replacements are needed, standard M3.5 electrical faceplate screws are widely available.

What other finishes are available in this range?

Knightsbridge produces this square-edge blanking plate in a range of finishes including polished chrome, brushed brass, polished brass, matt black and white. Use the search function or filters to find other variants in stock at Niori.
