Abstract

An electrical junction box particularly suitable for fabrication from molded plastic has a generally rectangular horizontal cross-section with a flat bottom wall, a pair of oppositely positioned flat side walls substantially parallel to each other, and a pair of end walls which are positioned opposite each other in a substantially parallel relationship, and which run between the edges of the side walls. A pair of hollow post members having a U-shaped lateral cross-section extend upwardly from opposite edges of the bottom wall along the opposite inner surfaces of the end walls. Each of these hollow post members has a bridge structure for supporting a fastener extending across the top thereof, this bridge structure having an aperture formed in its center for permitting the passage of an attachment screw. Slots are formed between opposite walls of the post members and the bridge structure, the arms of resilient fastener members being installed in the slots and retained therein by means of paired tabs which snap under shoulders formed in the walls of the post members. Sleeve receptacle members for receiving nails which can be used to attach the box to a wall stud or the like are formed…
