Underbody Toolboxes

Heavy Duty Truck Box and Trailer Toolbox – Mounted Underbody

We built these rugged boxes to fit the underbody of semi-trucks or any type of trailer. These storage boxes will give you easy accessibility and extra space to put equipment, tools, gear, or any device you may need while traveling down the road, or for the job at hand. They can be mounted on a semi-tractor, on the side of a trailer frame, or under a trailer deck. You can choose from side opening doors or drop down doors. The style of door depends on your needs and where you want to mount them. Our heavy duty doors include a t-handle lock system to keep all your gear safe and secure when you're not at your truck or trailer. We have three types of material to make your box including aluminum, powder coat or diamond tread. All our boxes are both high-grade and weather resistant.

We're an independent truck box manufacturer who has been building toolboxes and storage boxes since 1990. You can choose from one of our standard sizes, or you can custom order a size from us. We also have many colors available to choose from if your color scheme calls for a certain color. Give us a call and talk with one of our experts. We'll work with you to get it done to your satisfaction.
