Cable glands are metal or plastic screw-fit devices designed to provide splice protection and strain relief. Commonly used on hardware enclosures or leading into buildings, the concept is to allow a high level of cable integrity while allowing easier wiring maintenance. A common example of a cable gland is the wire inlet on the side of a high-voltage junction box, such as the type used for an attic fan or outdoor electrical join.

  1. 1

    Screw the enclosure end of the cable gland onto the enclosure or structural barrier by sliding in the main gland body, and securing with the nut.

  2. 2

    Push the incoming end of the wiring through the gland into the enclosure or structure, allowing sufficient length to complete the splice easily.

  3. 3

    Make the splice as needed inside the enclosure or structure.

  4. 4

    Slide the larger gland cap over the incoming wire. Screw the cap to the enclosure receptacle.

  5. 5

    Tighten the strain clamps around the both ends of the wire with the appropriate screwdriver.
