Fin-Tube 4″ lnsul., 50/pk
Insulators allow you to fasten electrified wire to posts without losing energy through the post.
Our Zareba® 4 Inch Fin Tube Insulator is made of durable, non-conducting UV-stabilized polyethylene. Designed for use with steel wire, the fins of this insulator prevent slipping, holding snugly in place. Its extra thick walls prevent voltage loss.
