Garvin CBC-800 Recessed Blank-Up Cover Plate, 8-Inch Diameter, Steel, White 8-INCH DIAMETER: The "blank-up" plate is used to cover the exposed hole left in the ceiling by unused & abandoned 6 or 7-Inch diameter can lights. ATTRACTIVE APPEARANCE: The smooth, white powder coated finish blends with white ceiling paint for a pleasing display in any finished space. STAY SAFE: The plate covers the entire fixture hole and prevents heat loss and risk of shock if the socket is energized and open. ECONOMICALLY EFFICIENT: The tapered, 1/4 outside edge seats firmly against the ceiling surface and prevents heat loss through the fixture opening as well as insect entry. EASY-TO-INSTALL: Screw the non conductive threaded hub into the light socket, and connect the spring to the hub eyelet and then stretch and connect it to the cover plate bracket.
