Garvin Industries rigid to EMT conduit couplings are used when an installer needs to convert from EMT to rigid conduit mid-run when they are installing an electrical raceway. These Combination Couplings allow an installer to quickly and easily switch from one type of conduit to another. One side of the coupling is threaded for Rigid pipe and the other side accepts EMT conduit. Quick compression glands bite tightly onto the EMT conduit.
