Gallagher's Standard Donut Insulators are frequently used at corners, dips, and rises to prevent electrical shorts between electrified wires and fence posts. This donut insulator is molded of high-density polyethylene with UV inhibitors for all-weather, long-lasting performance. You can securely attach a donut insulator by tying them to the post using wire or by mounting it on a lag screw. Once installed, the electrified wire can be run through the hole or on the outer groove of the insulator. These insulators come in a pack of 10 and have a 3-year warranty.
