Rod posts and step-in posts need an insulator that fits right and holds firm. The Black Round Post Insulator is designed for round posts from 1/4" to 9/16" in diameter, making it a natural fit for the fiberglass rod posts and step-in posts used in rotational grazing and portable fence systems.
The claw design snaps onto the post securely without tools, keeping the insulator in position and your wire properly isolated from the post. Whether you're setting up a new paddock or moving fence between grazing cells, these insulators go on fast and stay put under the tension of your electric wire.
UV-stabilized black polymer construction holds up in all weather conditions without cracking or fading. Sold in bags of 25.
