Rigid set screw coupling joins two lengths of threaded or unthreaded RMC or IMC to form a continuous raceway. It drives set screws that bite into the conduit wall, creating a direct metal-to-metal contact for a mechanically rigid and electrically grounded connection, all with a quick and tool-simple installation.
