Wadsworth Manufacturing has designed a new universal electric fence insulator designed to fit any wheel of a side-roll irrigation wheel line. Simply wrap the insulator around the wheel and hook it in the back. A quick-pull strap holds the wire in place. Wadsworth says this insulator will protect your irrigation systems from your cattle and keep them intact. It also works on wood posts, chain-link fence, and vinyl fence. The cost is $2 each.
