Raco 509 Gangable Switch Box 1 Gang Old Work

Product Description

The RACO 509 is a single-gang, gangable switch box designed for old-work electrical installations in residential wiring applications. Constructed from 0.0625-inch pre-galvanized steel, this box delivers durable corrosion resistance in standard wall cavity conditions. It provides 12.5 cubic inches of interior volume, meeting NEC fill requirements for typical device installations. The box measures 3 inches in height, 2 inches in width, and 2.5 inches in depth. Four 1/2-inch knockouts are positioned at the bottom and ends to accommodate conduit entry from multiple directions. Licensed electricians install this box during retrofit or repair work where old-work mounting is required.

The RACO 509 is suited for residential house wiring device installations where existing drywall or plaster walls are already in place. The gangable design allows two or more boxes to be joined side-by-side to accommodate multi-device configurations such as switch and receptacle combinations. Plaster ears are integrated to support flush mounting against finished wall surfaces in old-work scenarios. This box is a standard choice for retrofit switch and outlet locations throughout residential construction and light commercial tenant improvement work.
