Diabolical Inc Warranty
At a glance: manufacturer defects are fixed with a replacement part or, if needed, a whole new unit; lifetime coverage on the drawer slides Diabolical names
This is Diabolical Inc's policy, not an NVMOS policy. Diabolical doesn't publish a separate warranty document; its defect, damage and return terms live on its returns page, and we've summarized them in plain English. The manufacturer's official terms always govern and can change without notice. Last reviewed on nvmos.com: October 8, 2026.

Diabolical Van Passenger Seat Underseat Lock Box
Van seat bases are hollow, and that space is one of the best hiding spots in the vehicle if you can lock it. This kit gives you a locking front access panel and a closeout for the passenger seat base, turning it into a secure compartment for valuables, documents or electronics without taking up any floor or cabinet space in your build.
It works with swivel seats, which most camper builds use, and it still leaves room for an extra battery in the seat base. Diabolical lists it in its van collection alongside its Sprinter VS30 parts. Seat bases vary between vans and conversions, so if you're unsure about yours, call us at (920) 249-7744 before ordering and we'll help confirm fit.
