Seizmik's Dust Panel for the Kubota RTV400 & RTV500 is a rear panel that rolls up out of the way when not in use. It prevents the back draft that occurs when a windshield and hard top are used. This back panel makes riding in an RTV under adverse conditions much more comfortable because it keeps dust out, wind, and rain from entering the cab. It also fastens securely around the roll cage with velcro to give it a nice tight fit. A must have for your RTV. Highly requested item.
