The RAM-B-149ZU-A consists of a zinc coated u-bolt base, SHORT double socket arm and diamond adapter base. 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.
