The UWS crossover truck tool box is a trusted storage solution because it features our patented RigidCore lid design and enhanced aluminum construction. The lid is filled with a solid foam that strengthens it against bending or warping and it has a self-opening mechanism for convenient operation. This truck tool box is also built with extra-thick, 1-piece aluminum to be strong and highly resistant to corrosion. This particular model features a low-profile lid with 2 stainless steel paddle lock lift handles.
