Flatline Van Co. Universal Wheel Well Box
The Flatline Van Co. Universal Wheel Well Box transforms the most awkward, wasted space in your Sprinter, Transit, or Promaster van into clean, accessible storage.

A 1/2″ carbonized bamboo lid with integrated struts opens and closes smoothly, matching Flatline’s signature galley and cabinet aesthetic.
Beyond storage, the Wheel Well Box doubles as a sturdy bench or step stool, and its front toe kick features wiring cut-outs for running LED ambient lighting. Installation takes less than an hour and requires no special skills, making it an accessible upgrade whether you’re a seasoned van builder or tackling your first conversion.
