Spec'd Correctly Before It Ships

The vendor who sells you a 24-inch box when your flatbed rails require 18-inch mounting width — that's the problem we eliminate. Before your RC Industries underbody box ships, Tank Vault verifies your truck configuration, bed type, and size requirements against the available dimensions. Fifteen size options from 24-inch to 96-inch lengths, in 16-inch, 18-inch, and 24-inch widths, means there's a spec'd fit for most flatbeds, service bodies, and trailers. We cross-reference your mounting application with the correct EM Series configuration so the box that arrives matches the space you have. No return freight claims. No downtime waiting for the right size.

14-Gauge Steel Built to Handle the Job Site

14-Gauge Steel Built to Handle the Job Site

This underbody box uses 14-gauge steel construction — not the thinner sheet metal found on consumer-grade boxes that dent on the first rock strike. The stainless steel L hinge and heavy-duty door retainer chains are industrial-grade components designed for daily use on service trucks and fleet vehicles. The flush mount door sits recessed, reducing the chance of damage from loading and unloading. Whether your truck is on a construction site, a farm, or a municipal route, this box is built to last through years of exposure without structural compromise.

Weather-Sealed and Lock-Secured on Every Truck

Weather-Sealed and Lock-Secured on Every Truck

Automotive bulb weather sealing runs the full door perimeter, keeping rain, dust, and road debris out of your tool storage. The anchor compression latch with integrated cylinder lock provides a secure closure that resists tampering on unattended job sites. Available in single or double swing-down door configurations, the box gives you full access to contents without reaching deep into a recessed cavity. Three finish options — matte black, gloss black, and gloss white — let you match your fleet livery or keep a low profile on the underbody.

“Mounted two of these on our service trucks. The 14-gauge steel is noticeably heavier than the boxes we replaced, and the cylinder lock actually holds up to the job site. Weather seal has kept tools dry through three months of rain.”

Frequently Asked Questions

The EM Series is available in fifteen size configurations ranging from 24-inch to 96-inch lengths, with widths of 16, 18, and 24 inches. These boxes are designed to mount below the bed of flatbeds, service bodies, and trailers. Measure your available mounting space and select the size that fits your rail width and bed depth. If you are unsure which size matches your truck configuration, contact Tank Vault before ordering and we will help you verify the correct fit.
The RC Industries underbody box uses an anchor compression latch with a keyed cylinder lock. This is not a padlock loop — the lock is integrated into the latch mechanism, which makes it harder to pry open on an unattended job site. The flush mount door design also reduces exposed edges that could be leveraged for forced entry. For fleet applications where multiple crew members need access, contact Tank Vault about keyed-alike options for multi-box orders.
14-gauge steel. That is the body construction throughout the EM Series. The hinge is stainless steel, and the door retainer chains are heavy-duty rated. This is not light-gauge sheet metal — it is the material thickness you want on a box that gets mounted under a work truck and exposed to road debris, weather, and daily use. The flush mount design adds structural rigidity by recessing the door into the box frame.
Yes. The door perimeter uses automotive bulb weather sealing — the same type of seal used on vehicle doors. This creates a continuous barrier against rain, dust, and road spray when the door is latched. The anchor compression latch pulls the door tight against the seal. No underbody box is completely submersible, but the automotive bulb seal provides strong protection against normal weather exposure and road conditions.
RC Industries underbody boxes ship via LTL freight. Lead times vary by size and finish availability. Contact Tank Vault with your selected size and finish, and we will provide a current lead time before you order. These boxes ship free to your location — call or email if you need liftgate delivery, job-site drop, or specific delivery scheduling. We coordinate the freight details so the box arrives when your truck is ready for installation.
The EM Series is available in the fifteen standard sizes and three finishes listed on this page: matte black, gloss black, and gloss white. For non-standard configurations — custom dimensions, alternate finishes, or specific fitting requirements — contact Tank Vault before ordering. We coordinate directly with RC Industries for custom requests and will confirm feasibility, lead time, and pricing before any commitment.
Tank Vault offers a 30-day return window on uninstalled items in original packaging. If the box arrives damaged in freight, contact us immediately and we will resolve it — no runaround. For returns, the product must not show installation marks, drilling, or modification. Since these are heavy steel items shipped via LTL freight, we recommend verifying your size and fit before ordering. Our pre-offer spec review exists to prevent that situation.
