The RAM-B-108-GOP1U consists of a strap hose clamp ball base, double socket arm and 1" diameter ball with custom GoPro® Hero adapter. This solution provides a clean, rugged and low profile mounting solution for any rail diameter from 1" to 2.1". The GoPro® Hero adapter attaches directly to the under-side of the camera, replacing the factory mounting bracket. The patented double ball and socket design allows for infite adjustability while damping, so you can position your camera to the perfect capturing angle for any environment.
