The Chain-Up is designed to work with a weight distribution hitch or adjustable ball mount with rotating, multiple hitch ball sizes. Fits 2" and 2-5/16" hitch balls. The Chain-Up holds your trailer's safety chains up off the ground and keeps them from dragging while you are towing. The Chain-Up stays attached to your safety chains, and slips easily over the hitch ball during the trailer hook-up process. There is no faster or easier way to keep your safety chains from dragging!
