Utility Trailer Manufacturing Company's Utility Side Skirt, No. USS-120A-4, benefits from being U.S. EPA SmartWay verified to achieve greater than five percent fuel savings and can be used in combination with low rolling resistance tires on Utility trailers to achieve CARB (California Air Resources Board) compliance for California operations. Made with galvanized high tensile steel bracing, this allows the side skirt to flex both inward and outward, which can be bent back to their original shape if damaged. Built to last, it comes composed of UV protected bi-directional Fiberglass Reinforced Plastic (FRP) construction.
