Spec'd Correctly Before It Ships — Or We Don't Ship It

The wrong-size utility box showing up on your truck bed costs you real downtime — the same problem that plagues fuel tank buyers who receive incorrect bung configurations. Tank Vault applies the same verification process here. Before your ATB box ships, we confirm your selected dimensions, material type, and door configuration match your truck, flatbed, or trailer mounting requirements. No guesswork, no return freight claims, no three-week delays waiting for a replacement. The ATB box is fully seam welded on all seams and corners with a stainless steel continuous hinge running the full door length — industrial-grade construction that holds up to daily field use without flex, rust, or hinge failure.

Theft-Resistant and Weather-Sealed for Open-Air Job Sites

Theft-Resistant and Weather-Sealed for Open-Air Job Sites

Leaving tools on an open truck bed or flatbed invites both theft and weather damage. The ATB box addresses both with a lockable stainless steel Dolphin Tail HD adjustable T-handle latch and a rain gutter fitted with an automotive-grade weather seal. The door itself is channel-braced and reinforced, supported by an aircraft-type nylon door cable that prevents uncontrolled drops. Wider boxes include a three-point rod system for additional locking force at multiple points across the door span. The result is a field-proven storage enclosure that keeps your equipment dry and secure whether parked at a fleet yard, a construction site, or a rural farm operation.

Material Options Built to Match Your Work Environment

Material Options Built to Match Your Work Environment

Choose between .10-inch heavy-gauge aluminum tread plate, smooth aluminum in .09 or .10 gauge, or 14-gauge steel with a black powder coat finish. Steel variants receive a zinc epoxy primer beneath the MR powder baked topcoat for corrosion resistance. Aluminum construction reduces weight for fuel-sensitive fleet applications, while steel delivers maximum dent resistance for heavy-equipment environments. All variants share the same fully seam-welded construction and stainless steel hinge system. With eleven size configurations ranging from 24-inch to 90-inch lengths, the ATB line covers most truck-bed and flatbed mounting scenarios without requiring custom fabrication.

Compatibility Check

Confirm your mounting setup matches these requirements before ordering.

  • Mounting surface must accommodate selected box width (24"–90")
  • Requires truck bed, flatbed, or trailer with secure attachment points
  • Vertical available needed below mounting surface for drop-down door operation

Built for Real Work

Designed for professionals who store tools and equipment where they work — not back at the shop.

“Mounted a 48-inch tread aluminum ATB box on our service truck six months ago. Seam welds are solid, the drop-down door still opens smoothly, and the weather seal has kept everything dry through heavy spring rain. The T-handle latch feels substantial — not the flimsy hardware you get on lighter-duty boxes. Exactly what we needed for field work.”

Frequently Asked Questions

Three material configurations: .10-inch aluminum tread plate, smooth aluminum in .09 or .10 gauge, and 14-gauge steel. Steel boxes ship with a black powder coat finish over a zinc epoxy primer. Aluminum tread plate provides grip and dent resistance, while smooth aluminum reduces weight. Select the material that matches your work environment and mounting application.
The mounting kit is an optional add-on accessory, not included with the base box. Contact Tank Vault before ordering if you need the mounting kit added to your shipment. We can confirm compatibility with your truck bed, flatbed, or trailer mounting points and ensure everything arrives in a single delivery.
The drop-down door uses an aircraft-type nylon cable to support controlled opening. The door is channel-braced and reinforced for rigidity, with a stainless steel continuous hinge running the full door length. A rain gutter with automotive weather seal keeps moisture out. Locking is handled by a stainless steel Dolphin Tail HD adjustable T-handle latch, with wider boxes adding a three-point rod system for additional security across the door span.
Eleven size configurations across single and double drop-down door models: 24x18x18, 36x14x14, 36x16x16, 36x18x18, 48x18x18, 60x18x18, 63x14x18, 72x14x18, 72x16x24, 90x14x18, and 90x16x24 inches. Measure your truck bed or flatbed mounting area before selecting. Contact Tank Vault if you need help matching a size to your specific vehicle or trailer configuration.
The ATB box is classified as water resistant, not fully waterproof. The rain gutter with automotive weather seal prevents direct water intrusion through the door seam. However, the box is designed for mounting on trucks, flatbeds, and trailers — not submersion. For normal exposure to rain, road spray, and job-site conditions, the seal provides adequate protection for tools and equipment stored inside.
Tank Vault offers a 30-day return window on uninstalled utility boxes in original packaging. If the box arrives damaged or does not match your order specifications, contact us immediately and we resolve it directly — no runaround. Installed boxes or units with modifications are not eligible for return. Measure your mounting area and confirm your size selection before installation.
Lead times vary by size and material configuration. Standard sizes in aluminum typically ship faster than steel variants or uncommon dimensions. Tank Vault coordinates LTL freight to your site or a terminal near you. Contact us with your preferred size and material for a current lead time estimate, especially if you have a job-site deadline driving your purchase.
