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

Most crossover toolboxes give you one thing: a basic box you throw your junk into. The ADAPT Single Lid gives you a platform. Built from 10-gauge aluminum, which is 26% thicker than the 12-gauge industry standard, it mounts across the bed rails of any full-size truck 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 when your work and lifestyle demands it. The ADAPT system grows with you.

Why the ADAPT Single Lid Is Different

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
