IMMI SmartDock SCBA HolderNo Straps. No Levers. No Hassle. Firefighters should fight fires instead of their gear. With SmartDock, there are no cords or levers to slow them down. Simply bend at the waist to release the tank then stand up to exit the apparatus. In the event of a crash, SmartDock locks in place to keep the tank from becoming a projectile. A single model fits nearly all SCBAs, and SmartDock quickly retrofits to a wide variety of seats.
