What Is a Flatbed Truck?
A flatbed truck has an open bed instead of the typical one with sides and a tailgate on traditional pickups.
You can get a flatbed on pickup-style and heavy-duty trucks. These vehicles transport heavy loads or loads too large for a traditional truck bed.
Forklifts can easily load and unload with them, and you can even put a camper on them.
What Are Flatbed Truck Tool Boxes?
Because flatbeds don’t have sides, you need to use a different tool box than usual.
You can install them under the bed, on the sides, or at the front. Some have drawers, locks, and are constructed of various materials.

They open towards whatever side you install them on for easy access.

Headboard Roller Drawer Tool Boxes
A headboard drawer roller toolbox sits at the head of your bed, and you can access it via drawers on the side instead of opening the top.
