ELECTRICAL BOX WITH COUPLING MEMBERS Abstract of the Disclosure An electrical wall or ceiling box adapted to rapidly and securely couple an electrical wiring device thereto. The electrical box includes a pair of wedge-shaped inserts positioned within a pair of openings in the end walls of the electrical box. The inserts have a threaded, curved face portion for gripping a mounting screw and an oppositely facing sloping face portion for interacting with the sloping wall portions of the openings in the electrical box. The inserts also have a shoulder extending outwardly on three sides for engaging a three-sided ledge within the openings for retaining the inserts therein. This structure results in a significantly higher retention force than in prior devices, tending to resist disengagement of the inserts with the box upon insertion of a mounting screw therein.
