INSTALLATION INSTRUCTIONS
FOR ELECTRICAL CONTRACTOR

If you should experience an unforeseen problem, you can contact us at:

(800-654-8263) or Email us

  1. Attach the LESSCO Air-Vapor Barrier Box to the wall or ceiling framing member.
    1. If the nailing configuration or size of the electrical box requires, cut the top and bottom of the new, improved LESSCO Box where indicated. This allows the hinge action to take place. Then attach the LESSCO Box as in step one.
  2. Install standard electrical box inside of the LESSCO Box.
    NOTE: Steps #1 and #2 can be accomplished simultaneously by holding electrical box inside LESSCO Box, then attaching electrical box to framing member.
    1. If the hinge action is being used, simply swing the outward portion of the LESSCO Box away to provide more room to attach the electrical box.
  3. Make a small cut for wiring where indicated on the top or bottom of the LESSCO Box. Make only one small cut for each wire. DO NOT make one large hole for 3 or 4 wires.
  4. Install wiring through the LESSCO Box into electrical box. Complete wiring as usual.

    If the hinge feature is being used, DO NOT run the wire through the opening created by the cut made for the hinge option.
