Zareba Fence Insulators, Fin-Tube 4", 50-pk

The Zareba® 4" Fin-Tube Fence Insulators (50 Pack) are durable, non-conductive insulators designed to secure electrified wire to fence posts without losing energy through the post. Built from UV-stabilized high-density polyethylene, these insulators feature a ribbed fin design that grips firmly and resists slipping. With extra-thick walls to reduce voltage loss, they’re built to perform in any climate—because your fence should hold the charge, not give it away.
