Find heavy-duty electrical floor boxes, electric socket switch plates, and phone cable outlet covers for wood floors, mantels, and other hard duty locations. Brass and nickel covers for both single receptacles and duplex outlets. Sold as all-in-one units, cover plates are not sold separately, however replacement caps for Leviton brand floor electrical outlet plates are available. (If you need just the plate, the cheapest alternative is the data, phone and cable floor outlets.) By eliminating the need to stretch power cords across walkways and other high-traffic areas, floor boxes are the safe way to provide access to electrical receptacles when lighting fixtures, computers, phones, and other equipment require a power source that isn't near a wall.
