This is the Threaded Rod ONLY for this lift. For cows that cannot stand up on their own, such as right after giving birth. The gummed clamps are adjustable to the cow’s size. The lift is placed over the cow’s hips and tightened as necessary by cranking the handle, which secures the cow as she is lifted. This enables the cow to regain the use of her legs so she can be milked or treated.
