Use Bridgeport’s 600-DC2 3/8" Duplex Connector to connect and bond two individual pieces of flexible metal conduit or armored cable to an electrical box or enclosure using a single knockout. Die cast zinc connectors feature a precise fit and finish with excellent corrosion resistance for use in harsh environments. To install, simply insert FMC into the connector and tighten a single set screw to secure the conduit in place. Then, join the fitting with a 1/2" knockout using the provided locknut.
