Description

The UWS EC40012 is a gloss black aluminum 48" single-door topside truck tool box designed to mount on the truck's bed rail. It features an extra-thick, one-piece aluminum tub construction with welded seams for rigidity and protection against water and debris. A MicroSeal gasket ensures a tight seal when the lid is closed. The door opens 90 degrees downward, supported by aircraft-grade stainless steel cables rated for up to 1,000 lbs, providing full access and a handy platform. It includes a key-locking, stainless steel T-handle for durability and corrosion resistance. This product has a universal design, is made in the USA, and comes with a limited lifetime warranty (one-year finish, one-year parts). Heavy packaging is noted.
