3-1/2" deep, switch boxes with old-work clips and (6) 1/2" side knockouts and (2) 1/2" bottom knockouts are extra deep and used to support toggle switches, duplex devices, decorative devices and a variety of electrical outlets. Garvin Industries’ shallow switch boxes allow versatility of wiring design because they are gangable for multiple switches or device installations. Their plaster ears allow easy “cut in” when outlets or switches need to be added to existing shallow depth walls.
