Tractor Supply chest (in-bed) truck or trailer tool box. Black diamond plate. THIS IS NOT A CROSSOVER, OR BED RAIL TO BED RAIL BOX. IT SITS INSIDE THE BED. Bought new in August 2020 with the lifetime protection plan. Still have receipt,  and paid cash, so you would have no problem if you would need to use protection plan. DeeZee makes these boxes for TC and it has marked DeeZee lifters and hardware. Locks and lifters work perfectly. Carry handle on each end.. Top of box does have a couple small dents. Other than that nothing wrong with it. Paid $350 for box, plus $30 for protection plan, plus tax. Asking $325 OBO. Message me on here.
