ABSTRACT:
An electrical outlet box having wall areas recessed inwardly from the outermost periphery of the box wall structure, the recessed areas housing pawl mounting devices and electrical power cable entry ports. Each pawl mounting device includes a single stop flange on the outer surface of the box wall structure. The pawl arm includes a hub into which a threaded mounting screw is fastened and extends tangentially of the hub. The pawl arm terminates on one side of the hub in a right-angled stop flange and terminates on the opposite side of the hub in a small tab member. A guide channel adjacent the box stop flange slidably receives the pawl hub to guide the pawl in back and forth linear travel while the rear tab moves freely within a slotted channel formed between the box stop flange and the guide channel. The pawl arm and rear tab are alternatively urged against the box stop flange upon rotating the pawl in opposite directions causing the pawl to travel linearly in both a forward and backward direction.
