End/Corner Strain Insulators are used for ends to terminate, and corners to change direction of the fence line to create a seamless run of wire on the fence line. The bull-nose End/Corner Strain insulator in black uses a large center hole to accommodate poly wire, poly ropes, poly tapes, aluminum wire, and high tensile steel wire up to 1/2 in. These End/Corner Strain Insulators make sure the electrical conductor stays away from the posts as to prevent electrical shortages along the fence line. The bull nose insulator is UV-stabilized and made from a high quality fiberglass, reinforced with polyethylene. Available color is Black in a 25 pack and a 250 pack.
