The Dare 1703-C In-Line Strainer Silver is a corrosion-resistant tool designed to help tighten your high-tensile wire electric fence. A standard wrench ensures the strainer can easily be adjusted, while the compression clip applies high-tensile compression for a secure finish. It should be installed every 2,000 to 2,500 feet, and in positions that accommodate bends, dips or rises in the fence.
