Standard Donut Insulator

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.
