Spec'd Right for Your Flatbed Before It Ships

Spec'd Right for Your Flatbed Before It Ships

The vendor who ships a 72-inch box when your flatbed rail spacing needs 84 inches — that's the problem we eliminate. At Tank Vault, we verify your bed dimensions and mounting application before the order ships. If the size you selected doesn't align with your flatbed or service body configuration, we catch it. The RC Industries M Series is built-to-spec in .125-inch aluminum with ten size options from 72 to 96 inches in length, so you get the exact fit for your rig — not a return freight headache.

.125-Inch Aluminum Holds Up to Daily Job Site Use

.125-Inch Aluminum Holds Up to Daily Job Site Use

Industrial-grade .125-inch aluminum construction sets this box apart from thinner consumer-grade units that dent on the first impact. The pan-formed drop down door uses a stainless steel L-style hinge and heavy-duty retainer chains rated for repeated daily access. An automotive bulb seal keeps dust and moisture out of your tools and parts. Choose bright diamond plate for a visible, textured finish or smooth aluminum for a clean professional look. Either way, the box is field-proven for flatbeds, service bodies, and trailers that work for a living.

Cylinder Lock and Compression Latch Secure Your Inventory

Cylinder Lock and Compression Latch Secure Your Inventory

An anchor compression latch with integrated cylinder lock means your tools stay where you put them. This isn't a flimsy tab lock that a pry bar defeats in seconds — it's a compression-style latch that pulls the door tight against the bulb seal while the lock cylinder prevents unauthorized access. On a job site where tool theft is a real cost, this hardware matters. Double-door configurations on all sizes give you organized access from either side without exposing the full interior.

Compatibility Check

Verify your mounting surface before ordering to ensure proper fitment.

  • Top-side mounting surface on flatbed, service body, or trailer
  • Minimum 13" or 16" flat mounting width depending on box selection
  • Overhead available for 16", 18", or 24" box height

Built for the Job Site

Designed for professionals who mount storage where they need it — on top of the truck, not inside it.

“Mounted the 84-inch diamond plate on our service body. Solid construction, the drop down doors clear our bed rails perfectly, and the cylinder lock actually feels secure — not the flimsy stuff you get from the big-box catalogs. Tank Vault confirmed our dimensions before shipping.”

Frequently Asked Questions

Available in ten configurations: 72", 84", 90", and 96" lengths, each with 13"x16", 16"x18", or 16"x24" width and height options. All sizes feature double-door layouts. Weight ranges from 78 pounds for the 72"x13"x16" up to larger configurations. Select the size that matches your flatbed rail width and bed depth — contact Tank Vault before ordering if you need help matching dimensions to your specific truck or trailer setup.
The M Series is designed specifically for top-mount installation on flatbeds, service body trucks, and trailers. It mounts to the topside of the bed. Compatibility depends on your bed width, rail height, and available mounting surface — not on a specific truck brand. If you provide your bed dimensions and truck setup, Tank Vault will confirm the correct size before your order ships. No guessing, no returns due to wrong fit.
Diamond plate features a raised tread pattern that adds grip and hides surface scratches — practical for rough job sites. Smooth aluminum has a clean, uniform appearance suited for municipal fleets or operations that want a professional look. Both use the same .125-inch aluminum construction, so the structural strength is identical. The choice is cosmetic and functional preference, not a quality difference.
A crossover box sits between the bed rails with side-opening doors. The M Series top mount sits on top of the bed rail with doors that drop downward, giving you access from above. This design works well on flatbeds and service bodies where side access is limited by bed rails or tool trays. The drop down door uses heavy-duty retainer chains and a stainless steel L-style hinge to support the weight during use.
Lead times vary by size and finish selection. Tank Vault arranges LTL freight to your location — ships free to any address in the continental US. If you have a specific deadline, such as a truck build or fleet rollout, contact us before ordering and we will confirm availability and shipping timeline for your selected configuration. Job-site delivery and liftgate options are available on request.
Inspect the box on delivery before signing off with the carrier. If you find freight damage, note it on the delivery receipt and contact Tank Vault immediately. We resolve delivery damage claims without runaround — no sending you back to the manufacturer to file paperwork. Uninstalled boxes in original packaging are covered by our 30-day return policy. Document the damage with photos and we handle the rest.
