Flanged Coupler | Conduit Coupler

The flanged coupler has a rubber washer and brass threaded fitting. The couplers are commonly used for joining a run of conduit to a surface mounted socket or switch back box - like the Factorylux single and double back boxes. The coupler sits on the outside of the box and is secured by the brass bush on the inside. For joining lengths of conduit tube or female threaded conduit components, there are female couplers and male couplers.
