The Anchor Ring is designed to lift anchor systems up to 80 lbs. in saltwater, where 10 or more feet of chain are in use. Simply slip the 1/4" stainless steel ring over your anchor line, throw the buoy into the water, and motor forward around your anchor. The buoy will float the anchor to the surface, and the anchor chain will slide through the ring to counterbalance the anchor at the surface. Lifting capacity depends on the size of the buoy you choose to attach (sold separately). Assembly includes Anchor Ring, tether, and clip. Made in USA. Lifetime warranty.
