The RAP-B-138-GOP1 consists of a 2.5" diameter round base with the universal AMPS hole pattern, STANDARD size double socket arm and 1" diameter ball with custom GoPro® Hero 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. The RAM-B-138-GOP1 can be used as a drill-down or a temporary, removable mounting solution with the addition of the RAP-339U accessory. The GoPro® Hero adapter attaches directly to the underside of the camera, replacing the factory mounting bracket.
