The RAM-316-3-202U consists of the RAM POD III No-Drill™ vehicle base, three rigid aluminum rod legs, double socket arm and two 2.5" round bases that contain the universal AMPs hole pattern. 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 universal AMPs hole pattern found on the round base adapter will connect to many RAM cradles.
