The Single-Lid Series from UWS is a low-profile, crossover box with a single-lid opening for easy access. This multi-function utility box has a large lip that mounts on the truck bed rails, fitting snugly behind the cab. The two super-duty lift cylinders help to raise the insulated, beveled lid and hold it open to a full 90°. This box also features two stainless steel paddle-lift handles in the front of the box on both sides, with a lock on the driver's side that securely protects your gear from the elements and from theft. Single-lid boxes are the more widely preferred style box because of their easily accessible openings, large capacity and convenient features. Sturdy and strong, the Aluminum One Piece Tub and Lid is designed to support heavy loads, absorb tool drops as well as prevent leakages. The Crossover tool boxes are also available in two finishes; Bright Aluminum Diamond Tread or Topsider Black Powder Coated Diamond Tread to fit your work needs and your truck's style.
