*Steel EMT Set Screw Couplings are used in dry locations to connect the ends of two  EMT thinwall conduits together to extend the raceway.
*Our steel set screw couplings provide concrete tight connections when taped and properly secured with the included set screws, and are rated for electrical applications above 600 volts.
* Their heavy gauge steel construction maintains mechanical protection and solid grounding of one conduit to another.
* They are also zinc electroplated for excellent corrosion protection in damp locations.
* Set screw couplings are made with a versatile combination head screw that can securely fasten one conduit to another using a slotted, Phillips, or Robertson head screw driver.
