The Dare Wood Post Pinlock Insulator is designed for wood posts and built to withstand the pressure of high-tensile fencing, featuring a heavy cross-section and an attached pin that securely locks and unlocks fence wire. Its large flange prevents shorts and arcing, while the high-density polyethylene construction with carbon black ensures superior UV resistance and all-weather performance. The insulator comes complete with two galvanized nails for easy, reliable installation.
