Description The BT20 bezel accessory is a 380mm diameter grey polycarbonate trim ring designed to fit Knightsbridge BT20 LED bulkheads. The bezel clips or fixes around the perimeter of the bulkhead body, providing a neutral-toned finish that blends into grey-painted walls, rendered facades, or commercial environments where matching tones matter. Designed as a cosmetic accessory rather than a structural component, the bezel allows installers to match BT20 bulkheads to adjacent wall colours in corridors, stairwells, car parks, industrial units, and residential exteriors. The 52mm projection accounts for the depth added by the bezel ring once fitted to the bulkhead. The polycarbonate construction is impact-resistant and suitable for outdoor environments where UV exposure and temperature variation would degrade painted metal bezels. The grey finish is moulded into the material rather than painted, so surface wear from cleaning or contact does not expose a different colour beneath. Specification Diameter 380 mm Projection 52 mm Construction Polycarbonate Finish Grey Warranty 1 Downloads Product Specification Sheet Frequently Asked Which BT20 bulkheads is this bezel compatible with? The grey bezel fits all Knightsbridge BT20 20W LED bulkhead variants, including sensor models (BT20ACTS, BT20CTS), dimmable models, emergency models, and corridor-function models. See the compatible products list in the Description section above for the full range. Is the bezel supplied with the bulkhead or sold separately? Bezels are sold separately as optional accessories. The BT20 bulkheads are supplied with a white bezel as standard, so this grey bezel is purchased only when a colour match to grey walls or facades is required. Can the bezel be fitted after the bulkhead is installed? Yes. The bezel can be retrofitted to an existing BT20 installation by removing the original white bezel and clipping or fixing the grey bezel in its place. The bulkhead does not need to be removed from the ceiling or wall.
