1/4" edge taper white ceiling blank-up canopies with an 6" outside diameter are used on abandoned 4" and 5" recess can lights. They cover electrical wires and hide unattractive holes left by discontinued recessed light fixtures in ceilings. The tapered, 1/4” outside edge covers are perfect for hiding oversize box openings or drywall and plaster imperfections. The non-conductive plastic hubs thread into medium sockets while the spring tension keeps covers tight on ceiling surfaces.
