Underbody mounting brackets are sold separately.
The Buyers Products 1704305 black steel underbody truck tool box provides locking storage for small tools and equipment in a 24 in. H × 24 in. D × 36 in. W enclosure. Its recessed drop door opens downward, giving you access from the side of the truck while the box remains mounted below the body.
The body and door are 14-gauge carbon steel with a black powder-coated finish. A locking stainless steel T-handle compression latch draws the door against the D-bulb seal to help keep weather and road grime away from stored equipment. Choose this size by both the space available on the truck and the size of the tools you need to pass through the door opening.
Weather-resistant storage with serviceable hardware
Powder coating inside and out helps the steel box resist corrosion. The continuous stainless steel hinge and door cables support the drop-door arrangement, while the replaceable gasket can be serviced when worn or damaged. The box is made in the USA.

Plan the mounting arrangement
This box can be installed on a flat surface or beneath a truck body. An underbody installation requires suitable support brackets and a mounting arrangement matched to the vehicle frame. Additional fabrication may be needed. Have a qualified truck-equipment installer confirm the frame attachment, bracket support and clearances; the box dimensions alone do not establish vehicle fit.
