Chain-Up for Single Ball Mount

The Chain Up holds your trailer's safety chains up off the ground and keeps them from dragging while you are towing. They remain attached to your safety chains, and slip easily over the hitch ball during the trailer hook up process. The Chain Up for a single ball mount is designed to work with a standard stinger or ball mount, having just one hitch ball that is not adjustable. Fits either a 2 or 2-5/16 hitch ball.
