Use Bridgeport’s 533-DC 1-1/4" Screw-In Coupling to join two individual lengths of flexible metal conduit in a straight line. Die cast zinc connectors guarantee a precise fit, finish and excellent corrosion resistance for use in harsh environments. To install, simply screw coupling directly into grooved conduit. The coupling is ball burnished for a mirror-smooth finish. Bridgeport screw-in couplings come in flex trade sizes 1/2" to 2" and are all UL listed.
