Use Bridgeport’s 570-DCR2 3/8" Round Opening "U" Shaped Strap Connector to join 14/2 to 10/3 (.43" to .61") AC/MC cable to an electrical box or enclosure. Die cast zinc connectors feature a precise fit, finish and excellent corrosion resistance. To install, simply insert the cable into the connector and tighten down a single set screw to secure the cable in place. Then, secure the fitting to a 1/2" knockout using the provided locknut. This strap connector is also suitable for use with health care facility (HCF) and HCFMCI-A cabling.
