Use Bridgeport’s 3/8" Set Screw Connector to join flexible metal conduit (FMC), metal clad cable (MC), metal clad interlocking armor ground cable (MCI-A) and metal clad power control signal cable (MC-PCS) to an electrical box or enclosure. Die cast zinc connectors feature a precise fit, finish and excellent corrosion resistance for use in harsh environments. To install, insert the conduit into the fitting and then tighten the set screw with a screwdriver by hand. Then, secure the fitting to a 1/2" knockout are you’re done. Die cast zinc set screw connectors are listed per the standards in UL-514B.
