This RAM mount works perfectly with the iLevil series to facilitate installation. The RAM-B-166-UN7U consists of a 3.25″ twist lock suction cup base, double socket system, and universal spring loaded X-Grip® holder. The suction cup, twist lock base is designed to have a strong hold on glass and non-porous plastic surfaces, making it the ideal mount for your device, and providing a calibrating mechanism for the internal AHRS.
