Abstract
Electrical wiring box arrangements comprise a wiring box with end, side, and rear walls and a cable clamp. The wiring box wall structure is provided with knock-out regions, a first cable-engaging means, and means for attaching the cable clamp to a wall having knock-out regions. The cable clamp comprises a flexible flat sheet, attachable at one end to the box wall structure interior to the box. The opposite end of the cable clamp is provided with a foot portion, formed at an acute dihedral angle with the main body of the clamp. A non-metallic sheathed electrical cable inserted through a knock-out opening in the box wall structure, deflects the unattached end of the clamp inwardly into the box, engaging the cable against removal from the knock-out opening in an outward direction by the action of the first cable-engaging means and the heel of the clamp foot portion bearing oppositely against the cable sheath.
