Abstract: A plastic multi-section electrical wiring box assembled from a plurality of individual sections. The individual sections are constructed so as to be capable of being mechanically and physically interconnected with each other without the need for mechanical assembly apparatus. The various sections are further adapted to be used with a bonding material such as an adhesive or solvent welding material to insure positive, permanent connections between the various sections.

Abstract: An electrical wiring box having a pair of factory-installed mounting elements associated therewith for permitting the quick and easy mounting of an electrical device within the wiring box. The wiring box includes bosses each having a generally-rectangular opening countersunk therein for receiving a corresponding mounting element. Each of the mounting elements includes a central portion having a screw-receiving opening and a pair of abutment edge portions adjacent to the opening, a pair of spaced-apart side portions integral with the central portion, and a pair of deflectible thread-engaging portions integral with the side portions and including pairs of retention wing portions at the terminations thereof.
