Crossover, side-mount, chest and low-profile tool boxes, plus mounting hardware and locks — UnderCover, Unique Truck Accessories, Highway Products and more.
Style follows how you use the bed. A crossover box sits behind the cab and is the most common and the most secure, at the cost of bed length. Side-mount boxes leave the floor clear for full sheets of material. Low-profile boxes sit below the rail line so a tonneau cover can still close over them, which is the pairing most work trucks end up wanting.
Check three things: that the box fits your bed width at the rail rather than at the floor, that it clears the rear window when open on a crossover, and how the lid seals. A box that fills with meltwater every spring ruins tools regardless of how well it locks.
