Underbody Tool Boxes

Underbody Tool Boxes

Underbody tool boxes give you storage under the trailer or flatbed, so tools, gear, and cargo accessories stay protected without taking up deck space. Sturdy-Lite builds them in the USA from a high-strength aluminum alloy.

Underbody Tool Box Styles

Three styles are available. All mount on the curb side, and each has a mirror finish aluminum body that resists corrosion and cleans up easily, plus reinforced corners and a limited manufacturer's warranty.

Standard Double-Door Underbody Tool Box

This is the classic for daily use, and a favorite for haulers who want reliable access to tools while keeping the underdeck clear.

• Dual doors that open from the center for access from either side.
• A stainless steel lock rod that opens like a trailer door and can be padlocked for extra theft protection.
• A heavy-duty rubber gasket that makes the box weather resistant.

Flush-Door Underbody Tool Box

For a cleaner look, choose the flush-door tool box.

• The same double-door access, custom gutter system, and stainless steel lock rod as the standard box.
• Stainless steel strap hinges for added corrosion resistance.

Single-Door Drop-Down Wrecker Box

Built for the flatbed wrecker industry, this wrecker tool box has a load-rated door that opens downward for quick access to your trailer.

• A single full-width drop-down door, a good fit where a curb or other obstacle would stop double swing-out doors from opening.
• Load-rated door cables that are quieter than chain and won't catch on your tools.
• The same weather-resistant construction as the other Sturdy-Lite boxes.

Built to Withstand the Road

• High-strength aluminum alloy construction for lightweight durability.
• CNC-machined and laser-cut for consistent performance.
• All welds performed by AWS-certified welders.

Why Mount a Tool Box Under the Flatbed

An underbody box frees up cargo space and keeps essential gear organized and within reach, such as winch bars, winch straps, a fifth wheel pin puller, and extra oil.
