RACO fitting couples threaded rigid/IMC conduit to either threaded or unthreaded rigid/IMC or EMT conduit. Inside the unit, a universal compression ring secures the conduit. The Super Coupling saves time two ways; the coupling doesn’t need to be disassembled and the conduit doesn’t need to be turned. Field threading or turning conduit is a process required for traditional three-piece couplings.
Super Coupling provides installation ease in limited spaces. It’s lighter than traditional malleable iron 3-piece couplings. The zinc-plated steel fitting is UL Listed Concrete-tight. The fitting is available in four sizes, ranging from 2-1/2- to 4-inches.
