The RAM-B-138-GA63U consists of a 2.5" diameter round base with the universal AMPS hole pattern, double socket arm and Garmin VIRB™ camera adapter. 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. This mount is a drill-down mounting solution. The adapter attaches directly to the underside of the camera, replacing the factory mounting bracket.
