Monster Box 30 Storage Box for Sprinter
The best-selling rear door carrier on the market—entirely re-imagined. Capable of carrying an industry-leading 200 pounds of gear, the new B2 now comes with a complete Sherpa hole and slot panel, and even more modular capability.
Owl pioneered the Sprinter Ladder + Tire Carrier and is now the best-selling exterior part in the industry. It's hard to find a van without one. Years of development and testing have led to the lightest, strongest rear carrier on the market.
