Attach your GoPro to roll bars, railings or any tubes from 3.5 to 6.35 cm in diameter. The hinged, non-slip design is perfect for mounting to roof racks and more. The integrated base rotates 360° to let you capture shots from any angle at the push of a button. Move your camera between mounts on the fly with the included Vertical Mounting Buckle to enable multiple POVs for more dynamic footage.
