MAC-XC Magnetic Quick-Release for Helmet Air Pumper features robust Scosche magnets that facilitate quick connection and disconnection of the pumper hose to the roll bar-mounted coupler base. By attaching the Magnetic Hose Coupler to the included expandable hose, this creates an easy-to-use, magnetic connection. The kit also entails a MAC-XC magnetic helmet coupler and an expandable pumper hose that can stretch from 12 to 36 inches. However, the package excludes the Whip Mount and Bar Mount when the MAC-XC is only ordered. A Tube Size Reference Guide is provided showing compatibility with popular UTV bars.
