Description

The Knightsbridge 1-gang blanking plate covers unused electrical back boxes behind a gunmetal flat plate finish with just 2.5mm projection from the wall. The plate is cut from premium-grade steel and carries an IP20 rating, providing dust protection for back boxes where a socket or switch has been removed or relocated during rewiring.

Designed for residential, commercial and hospitality installations, the blanking plate fits standard 25mm single-gang back boxes and uses a built-in gasket to sit flush against the wall surface without gaps. The ultra-flat profile means the plate sits almost level with the wall rather than projecting forward like traditional screw-fixed plates, giving a cleaner finish in minimalist and contemporary spaces.

The gunmetal finish is a dark grey-brown metallic tone that pairs well with industrial interiors, exposed brickwork, concrete and polished plaster finishes. The 87.5mm square faceplate is secured to the back box with machine screws via an earth terminal, and the flat plate design leaves no visible screw heads once fitted. Certified to IEC 60670-1 and backed by a 25-year warranty.

Frequently Asked

What back box does this fit?

The blanking plate fits standard 25mm single-gang back boxes (also called 1-gang or 35mm boxes in some manufacturers' terminology). The 87.5mm square faceplate covers the aperture completely and the built-in gasket seals against the wall surface.

Why does it need an earth terminal?

The earth terminal allows the metal faceplate to be bonded to the earthing system in the back box, meeting UK wiring regulations for Class I metal accessories. This prevents the plate from becoming live if a fault occurs in nearby wiring.

Is the gunmetal finish the same as black nickel?

No. Gunmetal is a dark grey-brown metallic finish, while black nickel is typically darker and cooler-toned. The gunmetal has a slightly warmer undertone and is closer to pewter or aged steel in appearance.

What other finishes are available?

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