Single Lid Truck Tool Box Cutout 01

Single Lid Truck Tool Box

The most durable truck tool boxes on earth.

The last toolbox you'll ever need to buy!

Our Single-Lid saddle-style tool box suspends from pickup truck side rails, allowing clearance between the box and the truck bed. Constructed from 1/8-inch military-grade aluminum, these corrosion-free boxes provide superior security and a water-tight seal. The best feature of the Single-Lid is the giant opening, which makes it easy to organize and access your tools when open. Single-Lid Truck Tool Boxes are available in sizes to fit all pickup trucks and come standard with our lifetime warranty. Oh, and it's equipped with an under-the-lid bottle opener, because sometimes life is just tough.

  • 5052 Diamond Plate
    We build our Single-Lid Truck Tool Box from diamond plate 5052 aluminum, the same material used by the military, aircraft manufactures and boat builders.
  • Stainless Steel Hinges
    We use oversized stainless steel hinges and 1/4" stainless steel pins that are 302 spring-tempered.
  • Watertight Seal
    We use Clean Seal™ automotive stripping around the edges of our Single-Lid Truck Tool Box to ensure a watertight seal.
  • 10th Inch Aluminum
    All Highway Products Inc. tool boxes are made from the same material used by the military. This thick, lightweight material is the perfect solution for reducing the weight of your work truck.
  • Additional Tool Trays
    Need more room to hold smaller tools, drill bits, pipe fittings or knives? Don't want to reach down for in the bottom of your toolbox for them? Get an extra toolbox tray you can take out of the box and carry on-site.
  • Bottle Opener
    For those hard to open beverages at break-time or after work, we've included a convenient bottle opener built inconspicuously into the underside of the lid. Enjoy responsibly.
  • Gas Assisted Shocks
    Nitrogen-driven gas shocks raise the lid of your Single-Lid Truck Tool Box and keeps it open while you access your tools. The shocks are strategically placed so you can close the lid with one hand.
  • No Drill Mounting
    We engineered a special hook system that clamps the tool box to your pickup. This hook is accessed from inside and securely fastens to the side rail of your pickup bed. This eliminates the hassle of drilling holes in your truck.
  • Single Lid Design
    The single lid box design has an extra-large opening that allows unobstructed access your entire tool box.
  • T Handle Locks
    Our ergonomically designed T-Handle locks are the most secure locking mechanism on the market.
  • Tapered Design
    The tapered design of our tool boxes creates a larger opening, making it easier for you to reach items at the bottom of your tool box.
  • Welded Rope Hooks
    We've welded rope hooks directly to our Single-Lid Truck Tool Box which adds extra contact points for securing your load.
