Overview
UWS Under Tonneau Series Toolboxes
Compatible with most tonneau covers, the UWS Under Tonneau Series toolboxes are perfect for adding functional storage space and organization to your pickup while maintaining the option of keeping your truck bed covered. The under tonneau chest box features a low-profile, along with dual-locking handles, a RigidCore foam-filled lid and extra-thick, non-corrosive construction. The toolboxes' low-profile height of 16 1/2 in 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, and is built with enhanced security, featuring the UWS Secure Lock system. The two handles are both lockable and feature a connecting rod and pry-resistant rod enclosure. For versatility, 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.
Key features:
* Measures just under 16 1/2 in. tall to sit low in the truck bed and offer enough clearance for most tonneau covers
* Patented RigidCore foam-filled lid to maximize strength and prevent binding
* Extra-thick, one-piece aluminum tub holds heavy tools and cargo
* Easy-to-operate, dual-locking twist handles for enhanced security
* Connecting rod allows for convenient operation from driver or passenger side
* Interior rod enclosure helps prevent bending and jamming of lock system
* MicroSeal gasket helps seal out moisture, dust, and dirt
* Lid self-opens to 90 degrees for convenient operation and loading
* Manufacturer limited lifetime warranty (one-year finish, one-year parts)
* 90-degree lid opening operation may be limited by tonneau cover style
Notes: Includes tool box only (mounting hardware available #003-CBOXMK; sold separately).
