Use Bridgeport’s 591-DC2 1/2" E-Z Lock® Locknut Connector to quickly secure AC/MC cable to an electrical box or enclosure with minimal tools required. To install, push the cable into the rear of the fitting. The internal spring steel locking ring tabs securely clamp the cable in place and secure bonding. Then, to connect the fitting to the knockout, insert the connector and tighten the locknut hand-tight plus 1/4 turn. For use with AC/MC and MC-PCS cable from 10/2 to 8/3 (.54" to .73") in a 1/2" knockout. Bridgeport fittings come in a wide range of sizes and styles to provide complete installation flexibility. We build every product with the same goal in mind: guaranteeing a fast, professional-grade, trouble-free installation that meets or exceeds code requirements.
