About UWS
UWS, a Lippert brand, is a US manufacturer of truck tool boxes and truck storage accessories, with every aluminum box designed, fabricated, and welded at its Perry, Florida facility. The catalog runs from crossover saddle boxes and low-profile crossover boxes to side-mount boxes, wedge boxes, chest boxes, transfer tanks, drawer boxes, and dog boxes, built for the work-truck, ranching, and construction trades as well as everyday pickup owners. Most UWS boxes are built from 0.058-inch heavy-wall aluminum -- thicker than the 0.045 to 0.050-inch gauge common on budget boxes -- and finished with the brand's own patented RigidCore lid technology, a pair of aluminum plates inside the lid filled with hardening foam to stop the lid from flexing under load.
UWS backs its boxes with a limited lifetime warranty, with one-year coverage on finish and hardware, and pairs the RigidCore lid with a MicroSeal gasket and stainless-steel lockable T-handles or paddle handles on its crossover lines. On RevRated, the UWS EC10473 69-Inch Matte Black Heavy-Wall Aluminum Truck Tool Box with Low Profile, RigidCore Lid earned a top pick in our independent truck bed tool box testing, standing out for a one-piece welded aluminum tub and a low-profile lid geometry sized to clear the cab window line for tonneau cover compatibility.

UWS products we rated highly
UWS EC10473 69-Inch Matte Black Heavy-Wall Aluminum Truck Tool Box with Low Profile, RigidCore Lid
A one-piece welded 0.058-inch aluminum tub and a foam-filled RigidCore lid put this box in a different structural class than the thinner-gauge budget boxes we tested -- the lid does not flex under weight and the body resists denting from tools thrown across the bed. The low-profile geometry clears the cab window line on the half-ton trucks we installed it on, letting a roll-up or soft tri-fold tonneau cover seat flush instead of riding up over a tall lid. Self-closing pneumatic struts and a stainless steel paddle handle with RigidCore-reinforced latch round out the build, and the box carries a 4.5-star rating across 190 verified ratings on Amazon.
