100 Feet, Pre-Twisted Ultra-Wire

Pre-Twisted Underground Fence Wire The Quick Easy Way to Install Your Pet Fence Boundary Wire! Extra twisted wire. This is the same custom engineered ULTRA-WIRE included with our electronic fences. It comes pre-twisted for use in canceling the signal field in areas where you want your dog to be allowed to cross. Twisted wire cancels the signal field and does not trigger your dog’s receiver collar. You need twisted wire to connect your boundary loop to the transmitter and to create safe zones where your dog can safely cross buried wire. This allows you to create smaller boundaries within your yard to keep Fido away from the pool, flower beds and other off-limits areas. You get 100 feet of pre-twisted ULTRA-WIRE at an amazing value price!
