1-1/4" Set Screw
electrical couplings are used in dry locations to connect the ends of two 1-1/4”
EMT thinwall conduits together to extend the raceway. These Zinc Electro-Plated 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 screwdriver.
