Use Bridgeport’s 523-DCI2 1-1/4" Insulated Screw-in Connector to join flex trade size 1-1/4" flexible metal conduit (FMC) to an electrical box or enclosure. Die cast zinc connectors guarantee a precise fit, finish and excellent corrosion resistance for use in harsh environments. The screw-in design allows for quick and easy installation. The connector’s insulated throat protects inner wiring up to a temperature of 105°C. To install, simply screw the connector directly into the flexible metal conduit and then secure the fitting to a 1-1/4" knockout using Bridgeport’s legendary locknut. Insulated screw-in connectors are UL listed and come in trade sizes 3/8" through 2".
