Specifically designed with wide jaws for fitting Gallagher EquiFence or cord to wood posts and corner posts. The extra strength jaws can also withstand significant fence tension and keep wires firmly in place. W-insulators are easy to install and can be removed and reused with no damage to the post or the insulator. They deliver superior electrical performance, even under the highest voltages due to long leakage paths and protective shields. Tough and sun resistant, these insulators come with 10-year product warranty.
