The Zareba 500' 3-Strand Poly Wire has been designed for temporary fencing and is safer and more visible than traditional wire. It has 3 stainless steel constrictor strands and is lightweight, weather resistant and UV protected. This poly wire is portable, too, so it's easy to install, re-wind and re-use. Its lightweight (weighs 3 lbs per 1,000 feet), non-kinking design makes it great for your temporary fencing needs. Each roll contains 500 feet of yellow poly wire. Tensile strength is 151 lb/force.
