Your Gear Contained

The Unruli DEFENDER Box keeps up to 250 lbs. of your gear contained under the tonneau cover near the back of the pickup bed. Items won’t shift to hard to reach places or cause damage to your cargo and truck.

Your Gear Protected

Unruli’s integrated tonneau cover is waterproof and locks with your tailgate. Your cargo, gear and truck bed are protected – not just from shifting objects while in transit – but also from weather and theft.

Your Gear Within Reach

Say goodbye to reaching, climbing, and stumbling. Say hello to easy access to all your essentials. The built-in LED light even lets you see inside your cargo box in the dark.
