Abstract
A furred wall box assembly including a back plate, a top plate, and a cover plate. The back plate includes a base wall extending forward from its periphery. A plurality of knockouts are provided in the base wall. An outer wall extends outward from the front plate. Apertures in the front plate are aligned with and bosses in the back plate and fasteners used to secure the front plate to the back plate to form an outlet box within the joined front plate and back plate. A first flange is used to mount the box to a furring strip and a second flange is used to mount the box directly to the wall. A cover plate is mounted to the outer wall to complete the box assembly. The furred wall box assembly is especially useful for mounting an outlet box on a concrete masonry surface.
