No More Guessing With Exact-Fit Sizing

No More Guessing With Exact-Fit Sizing

The frustration of buying a toolbox that sits wrong or leaves gaps ends here. Unlike a one-size-fits-all approach, this saddle-style box suspends directly from your pickup truck side rails, creating clearance between the box and the bed floor. Available in three exact-fit widths—70" x 16" x 20", 70" x 16" x 23", and 70" x 16" x 27"—this vetted design eliminates the guesswork. No drill mounting keeps your truck intact while the rail-suspension mechanism ensures the box sits precisely where it belongs. Built for your truck, not just any truck.

Lock Down Your Tools Against Theft

Lock Down Your Tools Against Theft

Security isn't a suggestion when your livelihood sits in that box. Highway Products equips the Single Lid with a stainless-steel T-Handle, a ¼-inch thick stainless-steel piano hinge, and a 3/8-inch locking rod. These three components work together to resist pry attempts and forced entry far better than standard latch systems. The single giant lid design means one solid point of entry to defend, rather than multiple weak points. This curated selection from Truck Cover represents the kind of craftsmanship that justifies your investment.

Corrosion-Free Aluminum That Outlasts Your Truck

Corrosion-Free Aluminum That Outlasts Your Truck

Constructed from 1/8-inch high-grade aluminum, this box is engineered to resist corrosion through years of rain, snow, and road salt exposure. The water-tight seal keeps moisture out, protecting both the box interior and whatever you store inside. Available in multiple lid and base finishes—including Black Diamond Plate, Gladiator, Smooth Aluminum, and Smooth Black—you can match your truck's look without sacrificing durability. Every box ships free from Truck Cover and arrives backed by a lifetime warranty that reflects the manufacturer's confidence in their build quality.
