Compatible with most tonneau covers, the UWS Secure Lock under tonneau chest box is perfect for adding functional storage space and organization to your pickup while maintaining the option of keeping your truck bed covered. It features a low profile, dual-locking handles, a patented RigidCore foam-filled lid and extra-thick, non-corrosive construction. The UWS under tonneau tool box features profile height of 16-1/2". This helps maximize storage area within the box, while keeping it low enough to be compatible with most tonneau covers. The box is also built with an offset lid to add even more storage area without interfering with a rolled up tonneau cover. This under tonneau chest box is also built with enhanced security, feat uring the UWS Secure Lock system. The two handles are both lockable and feature a connecting rod and pry-resistant rod enclosure. The box can be locked on the driver side, passenger side or both, and once unlocked, it can be opened from either side, offering convenience without sacrificing security. To increase the strength and security of this under tonneau tool box even more, it features our patented RigidCore foam-filled lid. The lid is made up of two aluminum plates with a solid foam core between them, greatly increasing its rigidity and resistance to warping and binding. The lid is also equipped with a MicroSeal gasket along the entire seam, keeping out water, dust, dirt, grime and insects when the box is closed. The lid opens to a full 90 degrees and has self-opening gas struts for easy operation. To maximize structural integrity, the UWS Secure Lock under tonneau chest box is assembled in the USA with extra-thick 0.058" aluminum, welded together into a one-piece tub, allowing you to store all manner of tools, equipment, supplies and other cargo for the next job or weekend getaway.
