Daystars Winch Isolators provide a clean and easy way to store the winch hook when not in use. Installed over the winch cable, the Winch Isolators nest with a roller or hawse fairlead and provide a convenient rest for the winch hook that also prevents it from rattling. They do not affect winch operation and are constructed of a durable polyurethane material. Installation is a snap: simply remove the winch hook, slide the cable through the winch isolator, and re attach the hook its that simple!
