Take your mobile entertainment on the road with the new RAM Torque handlebar and rail mounting base. We have paired a B-sized 1in. rubber ball base that accommodates bars 1-1/8in. to 1-in. in diameter with a short length arm and the dynamic X-Grip for phones. Sizing inserts are included to provide a snug fit and offer additional protection for the rail. The mount utilizes nylon-insert locknuts to prevent loosening in high vibration environments. This low-profile mount is the perfect way to secure your personal electronics and small accessories in any high-vibration environment.
