Flatline Van Co. Van Rear Storage Box - Small
Description

Adding over 3.5 cubic feet of accessible, lockable storage space, it mounts directly to FVC Rear Door Platforms for Sprinter, Transit, and Promaster vans in under 30 minutes. The door doubles as a work surface, deploying to a flat counter position at 90 degrees via the included down-stay rod - perfect for trailhead prep or campsite cooking.
A weatherproof bulb seal and lockable latch keep your gear protected and secure no matter the conditions, while adjustable torque hinges let you dial in the door speed to your preference.

Manuals & Guides
FAQ
Does this storage box fit my van?
The Small Storage Box has universal fitment and is designed to mount directly to Flatline Van Co. Rear Door Platforms for Sprinter, Transit, and Promaster vans. If you already have an FVC Rear Door Platform installed, this box bolts right on with four hex bolts. It does not mount to factory van doors or non-FVC platforms.
Can I add a shelf inside the storage box?
Yes! The Small Storage Box is shelf-ready and compatible with optional half-depth or full-depth Storage Box Shelves sold separately by Flatline Van Co. Adding a shelf gives you even better interior organization for smaller items, tools, and gear.
Is the storage box waterproof?
The door closes on a weatherproof bulb seal and uses a weatherproof lockable latch, making the box highly weather-resistant and suitable for year-round exterior use. Two built-in drain plugs also allow for easy interior cleanup if any moisture does get in.
How does the door work as a counter surface?
The included down-stay rod props the door open at exactly 90 degrees, creating a flat, stable work surface - great for meal prep, gear staging, or any trailside task. If you want full access to the interior, simply remove the rod and the door swings open to 180 degrees.
Does this box come with mounting hardware?
Yes, stainless steel mounting hardware (four hex bolts) is included. Installation is designed to take less than 30 minutes when mounting to a compatible FVC Rear Door Platform. A full installation guide PDF is also available for download.
Can I lock the storage box?
Yes. The box features a weatherproof, lockable latch to keep your gear secure whether you're away from the van or on the move. This makes it a reliable option for storing tools, recovery equipment, or valuables in an exterior compartment.
