Barn Doors and Brute Capacity — The Aluminum Underbody Box That Works Like a Pro.

Contractors who run dual barn-door underbody boxes know the difference between light-duty and heavy-duty. The Chandler 24"W x 24"H x 60"L Smooth Aluminum Underbody Toolbox with Cam Locker Barn Doors is built for operators who need maximum opening access, serious security, and the weight savings that aluminum delivers on a fully loaded truck.

At 113 lbs, this all-aluminum box keeps gross vehicle weight in check while delivering more cubic feet of accessible, weather-sealed storage than most competitors can match.

The Aluminum Advantage — Maximum Access, Long-Term Value

Constructed from robotically welded 5052 aluminum (.125" thick) — the same alloy used in marine and commercial fabrication — this box is naturally corrosion-resistant and built to handle everything from coastal salt air to oil field dust without rusting.

The polished aluminum barn doors open fully from both sides, providing unobstructed access to the full interior — a major advantage over single-door designs when loading or retrieving gear in tight conditions. Full-length stainless steel piano hinges with .25" knuckles are huck-mounted on each door. Each huck-mount delivers 3,000 lbs of pull strength — 18,000 lbs total on the 6-huck cam locker bar latch system, making forced entry virtually impossible.

The 360-degree, 1-inch full-perimeter rain gutter channels water away from the door seal opening. An automotive-grade replaceable bulb seal runs the full perimeter for backup weather resistance. The stainless steel cam-over latch pulls both doors tightly against the seal when closed for maximum weather exclusion.

Inside, four 1/8" gussets on the corners add structural rigidity. Fully powder-coated interior protects your tools from raw metal contact. The cam locker latch and piano hinges are huck-mounted — field-replaceable without cutting or re-welding. Made in the USA, backed by Chandler's 10-year limited warranty.
