Unruli Cargo Boxes will not function with other brand tonneau or bed covers. Unruli tonneau cover rails must be installed for the cargo box to function properly.

Unruli Cargo Systems are not recommended for use with plastic drop-in bedliners. Spray-coated and fabric bedliners will need to have approximately a 1" square removed from each side of the bedliner for the system to fit in the bed properly. Other truck bed accessories that are installed along the top or on the inside of the truck bed may need to be removed prior to installation for the sliding rail system to function properly. Watch the Tonneau Cover Installation video for further information.
