Use Bridgeport’s 811-DC2 2-1/2" 90-Degree Connector to join flexible metal conduit to an electrical box or enclosure at a 90-degree angle. Die cast zinc connectors feature a precise fit, finish and excellent corrosion resistance for use in harsh environments. To install, simply insert the conduit into the connector and tighten the included set screws. Then, fasten the connector to the box using Bridgeport’s legendary locknut. It is for use with flex trade size 2-1/2" flexible metal conduit when installing through a 2-1/2" knockout.
