No matter what truck or trailer you’re operating, having secure, weathertight storage is a priority to keep straps, equipment and tools dry, safe and always on hand. The HD Ramps underbody trailer tool cabinets do just that. Built from 1/8” thick aluminum, they hold up to 400 lbs. of gear and come in multiple sizes for your application. A rubber weather seal around the inside of the door perimeter locks out moisture or grime.

Cam-locking mechanism accepts a padlock for security
Designed to keep in your straps, tools or equipment and keep unauthorized persons out, each toolbox features a secure cam-lock/lock rod mechanism that accepts a padlock of your choice. When not padlocked, the doors remain firmly closed to keep contents contained, unlike models with T-handles.

Toolbox installs underneath truck body for easy access
These toolboxes are easy to install under your truck body; either mount using your own hardware and brackets or purchase our specially-designed aluminum mounting brackets to match your toolbox dimensions.

Upgraded recessed door options for a sleek look to match your truck
All toolboxes ship out with standard recessed aluminum doors. If you’re looking to match existing truck accessories or simply want a different look on the face of your toolbox, we offer two upgraded door options. The set of polished aluminum doors feature more shine than the standard aluminum finish, and the set of stainless steel doors has a timeless look that will come across slightly darker than the standard aluminum toolbox body. Upon receipt, simply uninstall the existing standard aluminum doors from the toolbox and replace them with the upgraded doors.
How to Install the Door Upgrades
- Remove the aluminum doors that arrived with the toolbox
- Remove/unassembled the cam locking mechanism
- Install the upgraded polished or stainless doors
- Reinstall the cam locking mechanism onto the new doors
The standard aluminum doors may be stored or discarded at your discretion.
