Be good to your back with this all-steel, bolt-on swivel jack. Easy to attach and swings out of the way when not in use. New bolt-through swivel point increases strength and eliminates the old style snap ring. Swivel jacks have a 1,000-lb. capacity and fit up to 3 x 5-inch tongues. Lift: 25.3-inches. Saltwater models have rust-proof protection.
