The UWS topside truck tool box is the perfect way to add storage space to your truck, keeping your items safe, secure and accessible. It easily mounts onto the truck bed rail, leaving your truck bed open to haul other cargo. It features extra-thick aluminum construction, and it guards your valuables with a stainless steel lock system. Truck side tool boxes also come with strong, aircraft-grade stainless steel cables to fully support the door and a MicroSeal™ stripping to keep out grime and moisture. Like all UWS tool boxes for trucks, this product is proudly made right here in the USA. NOTE: This product is heavily packaged for parcel shipment.
