The Bridgeport #2-1/2 Steel Conduit Hanger with Nut and Bolt is used to secure 1-1/4” electrical metallic tubing (EMT) to a threaded rod, insulator supports or directly to a mounting surface. Each hanger comes with a 50 lb load rating and is crafted from steel and then plated with zinc. The steel body maintains a strong, durable connection while the zinc plating contributes to corrosion resistance in outdoor and harsh indoor environments. Conduit hangers come in trade sizes 0, 1, 2, 2-1/2, 3, 4, 5, 6, 7, 8 and 9. SKUs 2100-BN through 2140-BN come with carriage bolt and nut which frees both hands for installation. All others have a 2-way slotted/Phillips bolt with integral threads.
