Pair of mounting brackets only — tool box sold separately.
The Buyers Products 1701040 underbody truck tool box mounting bracket kit provides a pair of 24-inch-high × 24-inch-deep aluminum brackets for installing a compatible aluminum underbody tool box. Each bracket uses 1/4-inch formed aluminum angles with welded braces to support the mounting structure.
Made in the USA, these brackets combine low weight and corrosion resistance for truck installations exposed to weather and road conditions. Confirm the box dimensions, available mounting space, and frame attachment before ordering; the bracket dimensions alone do not establish compatibility.

Before ordering and installing
The tool box must have bottom support. Attaching a box only through its top, back, or sides can reduce its capacity and cause structural damage. Support the box along the full bracket and provide adequate attachment to the vehicle frame.
Truck and chassis layouts vary, so additional fabrication may be required. Buyers recommends installation by a qualified truck equipment dealer. Check for fuel tanks, fuel lines, brake lines, and wiring before drilling or welding, and inspect mounting fasteners monthly after installation.
| Check |
What to confirm |
| Tool box selection |
Verify the box model, material, dimensions, and required bottom support. |
| Vehicle clearance |
Check the frame attachment area, ground clearance, and access for opening the tool box. |
| Installation components |
Confirm the fasteners and any additional support or fabrication required for your chassis. |
| Operating load |
Verify the complete installation is suitable for the tool box and its contents; bracket size is not a load rating. |
