The BakBox is a collapsible cargo or toolbox that snaps onto the rail of any BakFlip tonneau cover. When it's installed and the cover is closed, nobody will even know that it's there. The BakBox flips out from the back wall of your truck to give you a full, secure tool chest and cargo management box. It disappears just as easily when you don't need it or simply need to use your full truck bed! The BakBox is 11 inches deep and 10 inches wide and up to 65 inches long, giving you a very generous size box behind your cab and can withstand up to 400lbs of weight, allowing you to store heavy tools or objects. The BakBox will keep all contents safe and dry when your BakFlip tonneau cover is closed. Carry tools, groceries, clothes, books, you name it, the BakBox will be there when you need it! The shifting tray allows management of small objects that can easily be slid out of the way or shifted from side to side of your way. Add ice and it becomes one incredible party chest! BakBox is built to last and easy to install! This product ships in approximately 1 days
