These adapter brackets make mounting Flatline’s Rear Storage Box (or the Ski & Snowboard Locker) onto an Owl B2 carrier as easy as bolting it in place—no modifications or drilling into the box required. Designed for builders who already run the Owl B2 system and want to add the convenience of Flatline’s rear storage options, these brackets create a reliable connection, merging functionality with simplicity.

At their core is a robust, 5 mm-thick aluminum bracket with a black powder coat finish, giving both sleek aesthetics and impressive structural strength. The design ensures that the storage box mounts securely across the span of the Owl B2, turning the carrier into a versatile gear platform.

Lightweight, durable, and compatible with both Sprinter and Transit B2 platforms, these brackets let you expand your cargo capacity without committing to permanent fixtures—or sacrificing style. It’s a modular upgrade that fits right into the adventure van toolkit.
