ABSTRACT:
A strain relief electrical cable fitting includes an externally threaded tubular body member divided by an inside inclined shoulder and outside flange into an upper compression chamber and a lower coupling section, a gland cap with a central top opening engaging the body member top thread. Housed in the compression chamber is an assembly of a rubber packing member and a nylon grip member, the packing member including an upper axially bored cylindrical section and peripherally spaced longitudinal fingers and the grip member including an upper ring encircling the packing fingers and abutting the cylindrical section underface and longitudinal fingers interdigitating the packing fingers and terminating in follower sections engaging the shoulder so that tightening of the cap compresses the packing member by way of a washer to advance and contract the grip fingers to clamp a fitting engaged cable and to contract the packing section bore and effect a hermetic seal of the cable.
