74.45 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/or third party tablet holders. Included in this package is hardware that will accommodate handlebars and 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^® C size 1.5" 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. This mount is ideal for securely mounting a tablet to a motorcycle or ATV/UTV vehicle.
