The Sumo Universal Rod Holder with Velcro Strap is great for strapping to the rail of a boat so the rod doesn't move during rough conditions. It can be used for party boats in the ocean or on your personal craft. Pier fishermen love it too because you can kick back and relax and not worry about your rod getting pulled over the side. it's made of heavy duty rubber with a strong and wide Velcro Strap.
