ABSTRACT:
A connector for connecting jacketed, metal clad cable to an electrical box includes a tubular metallic body with a stamped and formed retainer element preferably staked therein. This retainer element has an annular rim with radially inwardly directed fingers formed or bent toward the electrical-box end of the connector for permitting insertion of the cable therein preparatory to affixing the two together, for preventing withdrawal of that cable in the opposite direction, and also for providing an electrical grounding continuity. The connector also features an elastomeric compression grommet that compresses into the cable jacket upon the tightening of a nut onto the connector body. A Teflon washer between grommet and nut minimizes the frictional resistance therebetween as the nut is tightened onto the connector body.
