This Pole Cat is made of aluminum and is powder coated for durability. The clamp goes around the post, the swing arm closes and is held with a snap pin. Place your strap around the lift pin and attach to your lift equipment. The claws on it grab the post to keep it from slipping as you lift it with your equipment and guide it into the hole. Once the post is set and secured, let pressure off the strap- clamp will slide down the post, unhitch the pin and remove the Pole Cat. Ready for the next one.
