The RAM-166-202U consists of a 3.3" diameter suction cup twist lock base, 1.5" diameter double socket arm and round base adapter that contains the universal AMPs hole pattern. The suction cup, twist lock base is designed to have a strong hold on glass and non-porous plastic surfaces, including adhesive disks. The hole pattern found on the round base adapter will connect to many RAM cradles. 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.
