The RAP-B-202-GOP1-354-TRA1U consists of a Track Ball™ base, double socket arm and 1" diameter ball with custom GoPro® Hero adapter. The mount is designed with a RAM 1" diameter rubber ball and socket system that has adjustment points at both ends of the double socket arm - allowing for high adjustibility to achieve perfect viewing angles. The GoPro® Hero adapter attaches directly to the underside of the camera, replacing the factory mounting bracket. This kit is compatible with virtually any track system including the RAM Tough-Track™.
