Trunk Lockup Boxes Slide 1

Trunk Lockup Box

Keep your trunk organized and even more secure!

These units are tough and versatile. Plus, they're bolted down. They keep your cargo away from you in case of an accident. Law enforcement officers use them for easy access to firearms, ammunition, explosives, bullet proof vests, flashlights, and raid gear; as well as for storage of evidence. Veterinarians use them for drugs and vet supply. EMS personnel find them useful for securing drugs and medical supplies with room for a defibrillator on top. Firefighters find them essential for storing their heavy gear, portable radios, hard hats, fire shelters, Haz Mat, and pre-plan files.

Military Grade Aluminum

Highway Products uses nothing but the best materials. Our products are hand crafted out of Military Grade aluminum. Why take it that far? The days of using nothing but the best ingredients are all but gone in this world. We refuse to sink to that level. That’s the HPI difference.

Product Features

All HPI products come standard with options and features that you would normally pay extra for. Please explore all of our standard and optional features and call us with any questions you may have!

  • 4 Inch Top Rail Boxes

    Built from 1/8" heavy gauge, corrosion-resistant, marine-grade aluminum. No wood or rivets in these unique units. They are 100% welded, with nuts and bolts securing the locks and drawer slides. Our maximum-impact drawer slides provide full extension and are rated to handle up to 400 lbs, fully extended. Lockup boxes with 4" top rails are great for bulky quick-use items, or a spare tire that can be bolted down.

  • 8th Inch Aluminum

    All Highway Products Inc. toolboxes are made from 1/8" rust-free T6 6061 aluminum, the same material used by the military, aircraft manufactures and boat builders.

  • Angle Bracing

    One of the weak points of truck tool boxes is the bottom corners. There is so much road stress from carrying heavy tarps, chains, tools, and other equipment, the corners sometimes break. Highway Products has eliminated this problem with reinforced angle bracing welded in the corners.

  • Optional Dividers

    A divider option placed on one side of the underbody tool box keeps tie-down chains from drifting around the tool box, plus a hanging bar.

  • Stainless Steel Torx Screws

    Stainless steel Torx screws are the toughest fasteners on the market today. These fasteners won't loosen as you drive down the road and a door can be replaced without a special rivet gun.

  • T Handle Locks

    Our ergonomically designed T-Handle locks are the most secure locking mechanism on the market.
