Product Description

Truck Racks: Heavy-Duty Steel Top Rack Built for Flatbed Hauling Capacity and All-Weather Durability. Made in the USA by AMERICAN TRUCKBOXES ATB®️

This steel top rack with back gate is built for contractors, tradespeople, and fleet operators who haul long loads on flatbed trucks and need a secure, elevated storage rack that stays out of the way of cargo. The welded steel frame and back gate configuration give you a stable mounting point above the flatbed rails while keeping the full deck clear for hauling. Every rack is manufactured by American Truckboxes LLC in Blanchard, North Dakota. Custom lengths and fleet quantities are available for operators who need a size outside the standard range.

Key Features

  • Hauls up to 2,000 lbs: profession-grade design rated for heavy-duty flatbed loads
  • Outlasts the elements: welded steel construction resists the daily punishment of job site and highway use
  • Stops rust before it starts: powder coated with a durable undercoat and topcoat finish for long-term corrosion resistance
  • Bolts straight to your flatbed: weld-on mounting keeps the rack solidly fixed to the bed structure
  • Built-in back gate access: back gate opening with one or two side doors depending on size, for easy loading from multiple angles
  • Ready for job site visibility: integrated strobe light holder keeps your warning light mounted and secure
  • Sized for regular and crew cab flatbeds: available in lengths built to match different flatbed and cab configurations
