Raco switch boxes are designed to accommodate switches, receptacles and electrical outlets, as well as facilitate the construction of a system that can mount two or more devices side-by-side. These units feature plaster ears for use in old work applications, such as light switches & outlets and are best suited for use in 2-hour fire-rated walls. They further come equipped with nonmetallic sheathed cable clamps and bevelled corner boxes to prevent the clamp screws from protruding into the back wall.
