The RAM-316-3-240U consists of the RAM POD III No-Drill™ vehicle base, three rigid aluminum rod legs, double socket arm, 2.5" round bases that contain the universal AMPs hole pattern and 3.68" round base. The base of the mount connects to your seat rail without any drilling necessary. The rigid aluminum rod legs can be bent to position your device to its optimum viewing location. The mount is designed with a RAM 1.5" diameter patented rubber ball and socket system that has adjustment points at both ends of the double socket arm; this allowing for almost infinite adjustment and perfect viewing angles. The 3.68" round base contains pre-drilled holes that connect to RAM Tough-Dock™ Powered Docking Stations.
