Installation:

  1. Prepare the Conduit:

    • Measure and cut the EMT conduit to the required lengths using a pipe cutter or hacksaw.
    • Deburr the cut ends using a deburring tool or file to ensure smooth edges.
  2. Insert the Conduit:

    • Slide one end of the conduit into one side of the coupling until it is fully seated.
    • Repeat this step for the other piece of conduit on the opposite side of the coupling.
  3. Secure the Connection:

    • Tighten the set screws on the coupling using a screwdriver or wrench. Ensure the screws are tight enough to hold the conduit securely in place.
  4. Check the Installation:

    • Verify that the conduit is firmly connected and the coupling is properly aligned.
    • Ensure there are no gaps or loose connections.
  5. Tape the Connection (Optional):

    • For added protection, especially in outdoor or damp environments, you can wrap the connection with electrical tape to ensure it is concrete-tight

  • Pipe Cutter or Hacksaw
  • Deburring Tool or File
