ADAPT Single Lid Truck Tool Box

ADAPT Single Lid Crossover Truck Tool Box - Modular Bed Storage for Full-Size Trucks

Most crossover truck tool boxes give you one thing: a basic box you throw your junk into. The ADAPT Single Lid gives you a platform to build better storage and organization into your rig. Made in the USA from heavy-duty 10-gauge aluminum, that's 26% thicker than the 12-gauge industry standard, the ADAPT Single Lid Toolbox mounts easily across the bed rails of any full-size truck on the market and comes loaded with L-Track on both the interior and exterior. That means every drill, bucket, rack, and organizer you add locks into the same mounting system, repositions without tools, and stays put on the job.

Start here. Add more organization later when your work or lifestyle demands it. The ADAPT system grows with you and the way you use your truck.

Why the ADAPT Single Lid Is Different from Other Truck Tool Boxes:

• 10-Gauge Aluminum Construction - 26% thicker than the 12-gauge industry standard. Built to take abuse, not absorb it.
• L-Track Inside and Out - Interior L-Track organizes tools. Exterior L-Track mounts accessories to the outside of the box and expands into the full ADAPT system when you add a ladder rack or Topside boxes.
• Fits Any Full-Size Truck - Universal fitment. Mounts to the bed rails of full-size pickup trucks without drilling or cutting.
• Lifetime Warranty - Work hard. We've got you covered.
• Designed and Built in the USA 🇺🇸
• Available in Premium Black Powder Coat finish
