Buying these is a matching exercise. A trim has to fit a specific housing series, a lens has to fit a specific door frame, a wire guard has to fit a specific lamp envelope. That is why the product title usually carries the fixture model or series, and why the specification table on each page lists compatibility where the manufacturer publishes it. Sending us the fixture label or model number is usually faster than guessing from a photo.
This group covers fixture accessories, wire guards and lenses, exit and emergency parts, and the mounting and suspension hardware that goes with the fixtures we sell.
