RAM-B-149ZU consists of a zinc coated u-bolt base, standard double socket arm (RAM-B-201U) and diamond adapter base (RAM-B-238U). The diamond adapter base 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.
