ABSTRACT:
A cable clamp for use in an electrical box or the like for locating, holding and grounding cables fed into the box and through the clamp. The cable clamp is mounted within the electrical box adjacent the knock-out openings using a single fastener to retain one or two sheathed cables. The cables are clamped between walls of the clamp which includes an end abutment wall having a pair of apertures through which the conductor wires are fed. The abutment wall positionally locates the sheath of the cable. The clamping walls are brought together to retain the cable as the single fastener is tightened. The clamping walls include inner ribs which receive maximum clamping force via a stiffener flange and a small bearing surface to securely engage and position the cable. The cable clamp is integrally formed from a single piece of material, preferably steel.
