Example Step-By-Step Installation

In this example, we show a standard 2 x 4 wall with sheetrock on each side. Use these same procedures for any thickness material you want to pass high-voltage wire thru.

  1. #1. Drill a 5/8" to 3/4" hole through the surface you want to run the high-voltage wire thru.

    #1. Drill a 5/8" to 3/4" hole through the surface you want to run the high-voltage wire thru.

  2. #2. Choose the right length Pass-Thru for the job. In this case, it would be the 6" model.

  3. #3. Install the Pass-Thru through the drilled hole and secure in place with the nut on the rear side.

    Rear side / Front "neon" side (*side of the wall the neon will be mounted on).

    #3. Install the Pass-Thru through the drilled hole and secure in place with the nut on the rear side.

  4. #4. Install a Female Locknut on the rear side of the wall onto the threads of the Pass-Thru and tighten down.

    #4. Install a Female Locknut on the rear side of the wall onto the threads of the Pass-Thru and tighten down.

  5. #5. The Female Locknut is now installed.

    #5. The Female Locknut is now installed.

  6. #6. Cut a length of the Non-Metallic Greenfield to cover a high-voltage run from the wall Pass-Thru to your next connection point.

    #6. Cut a length of the Non-Metallic Greenfield to cover a high-voltage run from the wall Pass-Thru to your next connection point.

  7. #7. Simply "twist" the Non-Metallic Greenfield onto the male shaft located on the Female Locknut.

    #7. Simply "twist" the Non-Metallic Greenfield onto the male shaft located on the Female Locknut.

  8. #8. The other end of the Non Metallic Greenfield would either be routed to another piece of neon or a Metal Transformer Box as pictured. If going to a transformer box, a Male Locknut would be used. The Male Locknut would be bolted to a service knockout on the box, which would allow the Non-Metallic Greenfield to twist onto it. The installation is complete and ready for the high-voltage wire to be run through the installation.
