Use Bridgeport’s 230 1/2" Set Screw EMT Connector to connect electrical metallic tubing to an electrical box or enclosure. A steel construction and zinc plating makes this connector both strong and highly corrosion resistant in harsh environments. To install, simply insert 1/2" EMT into the fitting and tighten down the tri-drive slot/Phillips/Robertson head set screw to secure the tubing in place. Then, a fitted locknut is used to join the connector to a 1/2" knockout, creating a concrete-tight seal. Bridgeport set screw EMT connectors are available in trade sizes 1/2" to 4". All are UL Listed under File No. E24001.
