Industrial-Strength Aluminum That Refuses to Fail

Industrial-Strength Aluminum That Refuses to Fail

Fleet managers know the cost of a failed weld or a corroded box — downtime, lost tools, and replacement expenses that compound fast. This vetted RC Industries box eliminates that risk with .125 gauge aluminum construction throughout. Unlike thin-gauge alternatives that warp and crack under real-world use, this box holds its shape season after season. The continuous stainless steel hinges add another layer of durability where competitors cut corners with pinned hardware. Tank Vault selected this model specifically because it demonstrates the kind of craftsmanship that keeps your tools protected and your operation running without interruptions.

Full-Access Double Doors Without Obstructions

Full-Access Double Doors Without Obstructions

The double side swinging doors with no center post give you complete access to every inch of interior space. Two gas props hold the doors open while you load or retrieve equipment, so you are not fighting a heavy door with one hand. Two anchor compression latches keep everything locked down tight during transport. You can specify curbside or roadside opening to match your workflow and truck configuration. This curated design reflects real input from operators who need fast, unobstructed access to their tools on job sites where every minute matters.

Weatherproof Seal Protects Your Investment

Weatherproof Seal Protects Your Investment

An automotive bulb seal runs the full perimeter of the door opening, creating a barrier against rain, dust, and road debris. This is the same sealing method used in automotive applications where consistent, long-term weather resistance is non-negotiable. Three finish options — diamond plate, smooth, or smooth with 14 gauge stainless steel door — let you match the box to your truck or choose maximum corrosion resistance where conditions demand it. Seven sizes from 36"x18"x18" through 72"x24"x24" cover most underbody mounting requirements. This investment in proper storage pays for itself the first time your tools stay dry through a week of highway driving in wet conditions.

Compatibility Guide

Verify your mounting space using the measurements below before ordering.

  • Flatbed, service body, or trailer with exposed undercarriage frame rails

“We run six service trucks and switched to these RC boxes after our old underbody units started leaking at the hinges. The no-center-post doors make it way faster to grab what we need on site. The bulb seal actually keeps water out — checked after a week of rain. Solid box, worth every dollar.”
