Camrig Line Mount GoPro2

The CAMRIG Line Mount has been totally re-designed, and it's got what you need. A wider profile makes for incredibly stable video, and camera positioning always remains horizontal while riding.
The extended housing area is compatible with GoPro Premium Accessories, and the GoPro Floaty Back Door. Also included are 4 CAMRIG Line Mount Plugs - they help prevent any snags, make camera positioning easy and eliminate camera loss.
