ABSTRACT:
A clip system for accurately locating access openings in drywall panels for electrical outlets, junction boxes, conduit boxes, or other receptacles normally concealed within the wall. A plurality of resilient, disposable plastic clips are snap fitted to either the corners or the edges of various outlets, outlet covers, or similar structures requiring an access opening. Each clip comprises a resilient frame and a smaller, spaced apart, offset subframe that is yieldably deflectable. A deflectable wall connects the frame and subframe. A channel is formed between the frame and the subframe for captivating a portion of the outlet upon which the clip is forcibly inserted. Each clip supports a sharp, outwardly projecting prong that penetrates the drywall panel after installation. The clips occupy specific sections of the outlets, so that when the wallboard is installed, the tradesman may use the projecting prongs as a marking guide. Suitable bosses and internal configurations are employed to firmly grasp the outlet box when the clip is snap fitted, so that alignment is firmly preserved, even when wallboard is pressed against the clip prongs. The prongs can be removed easily prior to marking or cutting. The disposable clips need not be removed.
