The RAM-B-149Z-202U consists of a zinc coated u-bolt base, double socket arm and round base adapter. The round base adapter has a hole pattern that matches the industry standard AMPS hole pattern and will connect to a large variety of RAM Mount and third party cradles. Included in this package is hardware that will accommodate rails from 0.50" to 1.25" in diameter. A composite rail adapter can narrow the rail to a minimum width of 0.5”. The mount is designed with a RAM 1" 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.
