发明名称 Screw attachment pocket with guide tab
摘要 A molded electrical box is provided with attachment housings at opposite ends thereof. The attachment housing include a fixed arcuate surface and a movable partially threaded cam member to engage a screw inserted therein. A guide tab extends partially across the open front of the attachment housing and has an arcuate end surface to guide the screw between the engaging surfaces and prevent the screw from abutting a forwardly facing end of the cam member.
