Not all semi-trucks come with a storage area for tools and gears — but it’s a must-have for any trucker. Whether you need an underbody toolbox or a set of flatbed toolboxes for your fleet, you’ll find it in our wide selection of toolboxes for semi-trucks. Custom styles are also available to suit your specific needs.

As a top manufacturer for North America’s trucking industry, we make it easy for you to place your order. We have warehouses across the US, cutting down the delivery time significantly. You will get your new or replacement toolboxes, along with mounting kits, in no time, no matter where you are in the country.

Constructed of high strength/low weight aluminum. Protective coating on smooth L doors for improved shipping protection (to be removed at time of installation.)

Polished stainless steel T-handle latches with locks. Doors available in smooth finish or diamond plate. All smooth doors are polished to a # 8 grade for an exceptional appearance.


Our aluminum toolboxes for semi-trucks offer legendary toughness, delivering the following advantages:

Security and protection

Changing a flat or blown tire or replacing a clutch cable on the roadside is part of a trucker’s job. It’s a must-do for truckers to bring a set of go-to tools and gears whenever they hit the open road. But without secure storage, their tools can easily get stolen while they’re taking a break at rest areas or truck stops.

Rain, sunlight, and harsh temperatures can also wreak havoc on tools if they are left out in the truck bed. Our secure, durable toolboxes can protect your tools or those of your truckers from weather elements.

Better tool organization

With a truck toolbox, it’s easier to organize tools. You can find them faster whenever you need to do quick repairs on the roadside. This will save you a significant amount of time, whether you’re a truck driver, operator, or a fleet manager.

Visual appeal

Our toolboxes are made of aluminum complete with polished stainless-steel T-handle latches. Their doors are available in a diamond plate or smooth finish. But no matter which standard style you choose, our toolboxes can add a visual appeal to your truck. You can also opt for custom styles and designs.


Whether you’re a truck driver, owner, or a parts manager for an auto shop or truck dealership, you can’t go wrong with Merritt Aluminum Products.

High-quality, good-looking toolboxes

Made of high-strength/low-weight aluminum, our toolboxes are durable and sleek without adding any significant weight to your truck. Plus, with their superior strength, our toolboxes are the ideal choice for trucks operating in harsh environments.
