HD Ramps Lockable Underbody Trailer Toolbox 60"x18"x24" High-Strength Aluminum

Lockable Underbody Trailer Toolbox 60" x 24" x 18" — Aluminum, 400 lbs.

Chains, binders and straps thrown in the headache rack come out tangled and wet. Half the job at the shipper is finding the right chain.

This box mounts under the trailer and holds 400 lbs. of gear behind a lockable door. It measures 60" wide, 24" deep and 18" high, weighs 83 lbs empty, and is built from high-strength aluminum.

Why Choose This Underbody Trailer Toolbox

400 lbs. of lockable storage under the trailer, in aluminum rather than steel.

• 400 lbs. capacity — enough for a full set of chains and binders, not just straps.
• Lockable door (padlock not included) so the gear is still there in the morning.
• 60" wide — the useful dimension when you are laying chains flat rather than piling them.
• High-strength aluminum: it lives under the trailer in road salt and does not rust through.

Made For

Built for flatbed and step deck operators carrying a full securement kit.

• Flatbed and step deck carriers
• Machinery and equipment movers
• Steel, pipe and lumber haulers
• Owner-operators fitting out a new trailer
• Fleet shops standardizing trailer equipment

Features

• 400 lbs. — the rated load the box carries, so you can fill it with chain rather than guessing.
• 60" wide — chains lie flat instead of being coiled into a knot.
• 24" deep — takes binders and larger hardware, not just straps.
• 18" high — sized to standard underbody clearance on a flatbed or step deck.
• Lockable — the door takes a padlock — the padlock itself is not included.
• 83 lbs empty — the tare you add to the trailer before anything goes in.
• High-Strength Aluminum — aluminum rather than steel, because the box lives in road spray.
• Underbody mounting — uses bracket sets sized to the box, so nothing is improvised.

What Goes In It

A box rated at 400 lbs. is a chain box, not a strap box. That is the difference between a place to throw things and a place that actually holds a working set of securement.

The 60" width matters more than the volume figure. Chains laid flat come out one at a time; chains stuffed into a deep narrow box come out as one knot.

The door locks. On a trailer parked at a truck stop overnight, that is not a small feature.

Mounted Under the Trailer

Underbody is where the space is, and it is also the harshest place on the vehicle — road salt, spray, and grit off the rear wheels all day.

That is why this box is high-strength aluminum. Steel in that position rusts from the seams outward and the first sign is usually a door that will not shut.

Empty weight is 83 lbs. Fitted permanently, that comes off payload on every load, which is why the material choice is not cosmetic.

The Right Underbody Toolbox for Your Trailer

If your securement gear currently rides loose, this box gives it a locked home: 60" x 24" x 18", 400 lbs., aluminum.
