The Brophy RR06 is a heavy-duty, circular, rotating, zinc-plated steel, bolt-on, recessed tie-down rope ring, and it has a 6,000 lb. capacity. It is recessed to fit into the floor or wall of your trailer, so it will sit flush when not in use. It is designed to be bolted into place (mounting hardware not included). NOTE: This is for two (2) 6K Tie-Down Rope Rings.
