Overview
The RAM-B-149Z-347U consists of a zinc coated u-bolt base, double socket arm and square adapter base that contains the universal AMPS hole pattern. Included in this package is hardware that will accommodate rails from 0.50" / 1.27cm to 1.25" / 3.18cm 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" / 1.27cm. The square adapter base contains four pre-drilled holes at each corner, making the universal 1.5 x 1.188 (hole spacing) AMPS hole pattern. he mount is designed with a RAM 1" / 2.54cm 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.
