Spec'd Right for Your Truck Bed Before It Ships

Spec'd Right for Your Truck Bed Before It Ships

Wrong-size toolboxes cost you downtime. You order a 72-inch box for a short-bed truck, or pick the wrong drawer configuration, and now you're processing a freight return while your crew's tools sit exposed. Tank Vault eliminates that. We verify your bed length, rail width, and configuration needs before the order ships. The ATB Gullwing Crossover Toolbox is fully seam welded on all seams and corners with a reinforced bottom plate — industrial-grade construction that holds up to daily field use. Choose from four width options and multiple heights including low profile. Gas springs keep the lid open while you work. No guessing, no returns, no wasted time.

Weather-Sealed Lid Keeps Tools Dry in Any Conditions

Weather-Sealed Lid Keeps Tools Dry in Any Conditions

The ATB Gullwing Crossover uses a fully concealed rain gutter with automotive-type weather seal and an adjustable lock striker for positive closure. Stainless steel continuous hinges run the full length of the lid — no hinge gaps, no weak points. Push-in lockable stainless-steel latches secure both sides. Gas springs pop the lid open and hold it in position while you access gear. Channel-braced reinforced lid resists warping under load. This is field-proven protection for expensive tools and sensitive equipment that can't afford moisture exposure.

Aluminum or 16 Gauge Steel — Built to Match Your Duty Cycle

Aluminum or 16 Gauge Steel — Built to Match Your Duty Cycle

Select aluminum for weight savings or 16 gauge steel for maximum durability. Four dimension options span 62 to 72 inches in length with 20, 24, or 28-inch widths and 16-inch standard height. Low profile versions reduce height for visibility, and drawer configurations add organized storage with a sliding large tray and adjustable dividers. Removable dividers in the outer compartment let you customize the layout. Every configuration ships with the mounting kit. Heavy-gauge construction and full seam welding on all corners ensure this box outlasts lighter-duty alternatives.

Truck Bed Compatibility

This crossover toolbox mounts on top of your truck bed side rails. Verify your bed length and rail width before ordering.

  • Truck bed length matches 62" or 72" box option
  • Bed rail top surface is clear and unobstructed
  • Minimum 20" of rail-to-rail inside width available

★★★★★
“Mounted the 72-inch aluminum gullwing on three of our service trucks. The gas springs are solid, the weather seal has held through six months of rain and highway spray, and the latches still lock tight. We went with the drawer option on two of them — the organized storage cut our setup time on job sites significantly. First toolbox purchase where everything matched the spec sheet exactly.”

Frequently Asked Questions

Measure your bed rail width and the distance between your bed rails before selecting a size. The ATB Gullwing Crossover comes in 62-inch and 72-inch lengths with 20, 24, or 28-inch widths. Contact Tank Vault before ordering and we'll verify the right configuration for your specific truck and bed liner setup. We catch fitment issues before the box ships — not after it arrives.
Aluminum reduces overall weight, which matters if you're managing payload capacity across a fleet. 16 gauge steel delivers maximum dent and impact resistance for heavy-duty job sites. Both options are fully seam welded on all seams and corners with reinforced bottom plates. Choose based on your duty cycle — aluminum for highway fleets, steel for construction and off-road applications where the box takes direct contact.
The low profile aluminum with drawers option adds two drawers and increases total box height by 4 inches. The standard interior includes a sliding large tray with adjustable dividers, and removable dividers in the outer compartment. If you need organized storage for small tools, fasteners, or electrical components without digging through the main compartment, the drawer configuration adds that capability without sacrificing the gullwing lid access.
Yes. Every ATB Gullwing Crossover Toolbox ships with the complete mounting kit included at no extra charge. The hardware is designed for standard bed rail installation. If your application requires non-standard mounting — flatbed, utility body, or custom rack installation — contact us before ordering and we'll confirm compatibility for your specific setup.
Toolboxes ship via LTL freight. Lead time varies by configuration and material selection. Contact Tank Vault with your preferred size, material, and delivery zip code and we'll provide an accurate ship date. We coordinate freight directly to your site — call for liftgate or job-site delivery requirements if you don't have loading dock access.
Tank Vault offers a 30-day return window on uninstalled toolboxes in original packaging. If the box arrives and the dimensions don't work for your application, contact us immediately. That's exactly why we offer free pre-offer spec review — to verify fitment before you order. Measure twice, confirm with us, and the box arrives spec'd correctly the first time.
The ATB Gullwing uses a fully concealed rain gutter system with an automotive-type weather seal and an adjustable lock striker for positive closure. The stainless steel continuous hinge runs the full lid length with no gap points. This is the same sealing approach used in automotive applications — not a foam strip stuck to the edge. For field conditions, this is serious weather protection.
