The Rugged Ridge Winch Line Stopper is constructed of heavy duty rubber that will compress under load, keeping the winch line and hook tight without damaging your hawse or roller fairlead. The Stopper acts as an isolator and eliminates obnoxious hook rattle when the winch is spooled in. Unlike other models, the Rugged Ridge® Winch Line Stopper is easy to install and does not require removing the hook or cable. The Stopper can be used with steel or synthetic winch lines up to 3/8 inch and with roller or hawse fairleads. The beefy stopper weighs 8 oz. and measures 3.25 inch x 1.75 inch. Great for full size winches or ATV/ UTV Winches!
