Product Description
Semi Underbody Toolbox: Super HD 12-Gauge Steel Protection for Trailer Gear. Made in the USA by AMERICAN TRUCKBOXES ATB®️
This semi underbody toolbox is built for over-the-road drivers and fleet operators who need a rugged place to lock up chains, binders, and the miscellaneous tools every trailer run demands. The 12-gauge steel body and Super HD construction stand up to daily loading, road vibration, and weather without flexing or rattling loose. It is manufactured by American Truckboxes LLC in Blanchard, North Dakota. Custom sizing and fleet quantity orders are available for operations that need a consistent toolbox spec across the yard.
Key Features
- Keeps water out: fully concealed rain gutter routes runoff away from the door seam instead of letting it pool on stored gear
- Seals tight every time: bulb-type automotive sealing door gasket compresses against the frame for a positive weather-tight closure
- Built to take a beating: 12-gauge steel construction rated Super HD for the constant vibration and load cycling of semi trailer service
- Locks down fast: Dolphin Tail HD T-handle lock secures the door with a single quarter-turn motion, even with gloves on
- Finished to last: powder coated black MX finish resists chipping and corrosion from road salt, gravel, and fuel splash
- Sized for the job: available in a 60 inch wide single door configuration or a 72 inch wide double door configuration for larger tool and chain loads
- Mounts where you need it: designed for underbody trailer mounting, compatible with M2100 Series mounting brackets for C-frame or I-frame installation
