Double Loop Layout with Exclusion Areas
Double Loop Layouts are needed when certain areas of the property do not need containment. This requires the wire to be double backed on itself so that it can still create one single loop back to the wall unit

This layout is ideal when you are containing a portion of your property, but also want to keep your out of certain areas within the containment area. The highlighted graphic indicates where the pet is allowed to go.

To lay a Double Loop with exclusion areas, lay the wire around the perimeter of the area you want to contain. Once you get to the end of the area you want to contain, step inward 3-5 feet and follow the same path back. With a separate piece of wire, encircle the area the pet is not allowed as well. Connect the two areas using twisted wire. Once you have completed the loop and back where you started, you can splice in your twisted wire to plug into your wall unit.
Twisted wire allows the pet to cross over the wire without receiving a correction. It is needed to connect your wall unit to your boundary wire. The wire needs to have 10-12 twists per foot to adequately cancel the signal. Pre-twisted wire is recommended and can be purchased HERE. The wire can also be twisted manually or utilizing a drill as seen HERE.
