Gallagher's Wood Post Equi "W" Insulator is specifically designed for Gallagher EquiBraid, EquiFence, and 1/2" Poly Tape and Turbo Tape. It easily attaches to wooden posts, and its extra-large shield eliminates power leakage through tracking. It's made from UV-resistant, polyethylene plastic for longer life, and the new flexible jaw design will release the wire if an animal collides with the fence. | Gallagher Wood Post Equi "W" Insulator in White | Size 25 Pack
