Twisted wire creates "gates" where your dog can safely cross buried wire. This allows you to fence off "island" areas within your yard - perfect for pools, play sets, or other off-limits areas. Also, very helpful for layouts where the fence needs to be distant from the transmitter. Saves installation time. 100 Feet of Pre-Twisted 20-gauge Boundary Wire
