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 under-side of the camera, replacing the factory mounting bracket.
