The RAP-B-383-GA63U consists of a quick release track base, double socket arm and Garmin VIRB camera adapter. Designed to accommodate all kayak tracks, as well as common track systems, engage and fasten the base to your existing track system or many other's including SlideTrax and the common T-Track. With a quick turn of the ball the base will slide along the track, giving you ultimate flexibility in repositioning your camera. A necessity for the all kayak enthusiasts, the RAM Quick Release Track Ball Base is certain to create more mounting options on whatever you choose to take to the water. The mount is designed with a RAM 2.54cm (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 adapter attaches directly to the underside of the camera, replacing the factory mounting bracket.
