FOLDED METALLIC WIRING BOX Abstract of the Disclosure Formed metal electrical wiring boxes possess integral wiring device mounting members which permit the facile push-insertion of the wiring device mounting screws, but which firmly engage the mounting screws once tightened down. The mounting members comprise a flat portion attached to each endwall of the wiring box and formed at right angles to the endwalls. Opposed leg portions are attached to the flat portion, and are folded downwardly along the box endwalls. The leg portions terminate in opposed foot portions spaced apart from one another by a distance less than the diameter of the wiring device mounting screw. A mounting screw inserted through an aperture in the flat portion and between the opposed leg portions contacts the opposed foot portions forcing the leg portions apart to permit the push-insertion of the screw. Turning the mounting screw draws the opposed foot portions upward, forcing them against the screw threads to firmly engage the screw.
