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

Ordering the wrong size generator box means wasted freight, downtime, and a return claim. That's exactly what our pre-offer spec review eliminates. Before your ATB box leaves, we cross-reference your generator dimensions against the 16 available size configurations. The fully seam welded aluminum construction, stainless steel continuous hinge, and channel braced reinforced lid are consistent across all sizes — but the fit has to match your generator exactly. We verify that before the order processes. No guessing. No measuring twice at the job site. Tell us your generator model and mounting location, and we confirm the correct size from the spec sheets.

Seam-Welded Aluminum With Stainless Steel Hardware Throughout

Seam-Welded Aluminum With Stainless Steel Hardware Throughout

Every ATB generator box is fully seam welded on all seams and corners — no rivets, no fasteners that back out over vibration. The stainless steel continuous hinge runs the full length of the door for smooth operation under load. A lockable stainless steel latch with adjustable lock striker maintains a positive weather seal in transit and on site. Durable stainless steel intake and exhaust grills on the left, right, and back provide ventilation, with a front access panel for convenient maintenance access. This is industrial-grade enclosure construction, not a consumer-grade storage bin.

Mount Anywhere — Top or Side, Truck or Trailer

Mount Anywhere — Top or Side, Truck or Trailer

The ATB top-open box mounts on top or on the side of your truck or trailer, giving you flexibility based on your equipment layout and available space. A channel braced reinforced lid adds structural rigidity for top-mount applications where the box takes direct load from above. An optional front door grill adds additional ventilation access, and an optional mounting kit simplifies installation. A minimum 5-inch available from the air grill face is required on the full intake and exhaust side for proper air movement — we flag this during pre-offer spec review so your generator runs correctly on day one.

Fit Check

Select a box size that accommodates your generator dimensions with room for the required air grill available.

  • Generator width is less than the selected box internal width
  • Generator depth is less than the selected box internal depth
  • Minimum 5 inches of available on all air intake and exhaust grill faces

“Ordered the 24x32x24 for our trailer-mounted generator. Tank Vault confirmed the size fit before I pulled the trigger. Box arrived fully welded, no gaps, stainless hardware throughout. Mounted it on the side of our trailer with the optional kit. Lockable latch keeps it secure on job sites.”

Frequently Asked Questions

Contact us with your generator make, model, and overall dimensions. We cross-reference against the 16 available ATB size configurations to confirm the correct fit before you order. The box needs to accommodate your generator with adequate available around the intake and exhaust grills — a minimum 5-inch distance from the grill face is required for proper air movement. We verify this during our free pre-offer spec review so you don't end up with the wrong size on delivery day.
The ATB top-open box mounts on top or on the side of your truck or trailer. An optional mounting kit is available to simplify installation. The key consideration is ensuring your mounting surface can support the loaded weight of the box plus your generator, and that the 5-inch grill available requirement can be met at your chosen mounting location. Tell us your vehicle type and mounting preference during pre-offer review and we'll confirm compatibility.
Lead times vary by size configuration. Contact us with your required dimensions and we'll confirm current availability and ship date before you order. Tank Vault arranges LTL freight nationwide — ships free to your site. If you have a job site deadline, let us know upfront and we'll verify the timeline is achievable. We don't promise dates we can't hit.
The mounting kit is an optional add-on, not included by default. Select it at checkout if you need mounting hardware for your installation. The box itself includes the lockable stainless steel latch, adjustable lock striker, continuous hinge, and all welded structural components. Optional front door grill is also available as an add-on for additional ventilation access.
The ATB generator storage box is constructed from aluminum with full seam welding on all seams and corners. Hardware is stainless steel throughout — continuous hinge, lockable latch, adjustable lock striker, and intake and exhaust grills on the left, right, and back. The lid is channel braced and reinforced for structural rigidity. This is industrial-grade enclosure construction designed to withstand vibration, weather exposure, and field use.
That's what our free pre-offer spec review prevents. We verify your generator dimensions against the 16 available sizes before the order ships. If a box arrives and doesn't fit your application, contact us immediately — uninstalled units in original packaging are covered by our 30-day return policy. We resolve it directly, no runaround. But the better path: let us spec it right the first time.
Yes. A front door grill is available as an optional add-on. The box comes standard with durable stainless steel intake and exhaust grills on the left, right, and back sides, plus a front access panel for maintenance. The optional front grill adds additional airflow capacity if your generator requires it. Contact us before ordering and we'll advise whether the standard ventilation configuration is sufficient for your specific generator model.
