The RAM Quick-Grip XL Phone Mount with Grab Handle M6 Bolt Base from RAM MOUNTS holds phones 5.75 to 7.25' in height, 2.625 to 3.625' in width, and 2 lb in weight. An aluminum and composite construction makes for a durable holder that lasts longer. The ball joint allows for motion in each axis to perfect your viewing angle. This mount uses an M6 bolt connection made for vehicle grab handles that include a 6mm or smaller bolt to avoid drilling when installing. This way, your windshield stays clean, your dash stays clear, and your phone stays out of the way while still in reach. This mount has confirmed fitment for the Toyota Tundra and all Ford Bronco models. Please note that using a bolt smaller than 6mm decreases the load capacity below 2 lb.
