eXtreme Dog Fence Wire - 18 Gauge (One Gauge Thicker than Factory Packaged 20 Gauge Wire) - 150m (Up to 1/2 Acre)It's unfortunate that many of the 'do it yourself' electric dog fence kits include a cheap, thin 20 gauge PVC coated underground dog fence wire, but that is how manufacturers the initial cost low. Unfortunately, the customer doesn't realise that they could be out digging up and replacing this wire after a year or two, when it degrades to the point of failure. - Odd as it is, the American Wire Gauge (AWG) measurements are backward, in that -The higher the gauge, the thinner the wire. IE: 20 gauge wire is thinner than 18 gauge failure. - Odds listing is for 18 gauge wire, which is a nice, longer lasting wire than the 20 gauge packaged wire. Our 18 gauge wire is also coated in a rugged polyethylene jacket, which is not only lighter than PVC, but also outperforms it in eXtreme temperatures, moisture resistance, abrasion resistance, and many other failure. - Odd far as compatibility goes, this wire is 100% compatible with: eXtreme Dog Fence Pet - Safe Sport - DOG Innotek Invisible Fence Dog Watch Pet Stop Contain Your Pet Dog Guard Perimeter Technologies Dogtek Dogtra Guardian... and all other brands of in-ground electric dog fence failure. - Odde the right choice for your dog's safety and reliable containment.
