The RAM-B-231Z-366U consists of a zinc coated u-bolt base, double socket arm and 1″ ball, connected to a round plate with 1/4″-20 camera thread. Included in this package is hardware that will accommodate rails from 0.50″ to 1.25″ in diameter. The base includes black cover caps to be placed over the exposed ends of the u-bolt. The included composite rail adapter can narrow the rail to a minimum width of 0.5″. The male 1/4″-20 threaded steel stud will connect to any standard female thread found on camcorders, digital cameras and POV cameras. 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.
