Product Description

Semi Truck Saddle Box: Heavy-Duty Aluminum Storage Built for the Space Between Your Fuel Tank and Rear Tires. Made in the USA by AMERICAN TRUCKBOXES ATB®️.

This saddle box toolbox is built for owner-operators and fleet drivers who need secure, weather-tight storage mounted low along the truck frame. The single drop-open lid gives you quick top access to chains, straps, and tools without stepping up or reaching over a step deck. Every box is manufactured by American Truckboxes LLC in Blanchard, North Dakota. Custom sizing and fleet orders are available directly from the factory.

Key Features

  • Resists corrosion for the long haul: durable aluminum construction holds up to road salt, moisture, and daily wear better than painted steel
  • Stays put on the frame rail: reinforced back panel is built for mounting between the fuel tank and rear tires on a semi truck
  • Quick, simple access: single drop-open lid swings down for fast top loading without a stepped profile getting in the way
  • Clean, smooth finish: all-smooth aluminum exterior for a finished look without the diamond-plate texture
  • Break-in resistant lock: DT-handle lock secures the lid against theft and tampering
  • No steps to snag or catch: low-profile saddle design keeps the box tucked close to the frame
  • Backed by decades of build quality: over 25 years of American manufacturing experience behind every weld
