TheRock is a traditional non-cutaway mount with some features not seen in other mounts. The mount includes detents which make the angle setting rigid. This mount will not only reduce snagging hazards but will also maintain the perfect angle setting if it gets bumped.
There are angle setting marks on the side of the mount. When removing and reinstalling, your preferred angle setting is easily repeatable and the markings quickly let you know that it is set properly.
Installation is a breeze. The kit comes with all necessary hardware including an appropriately sized drill bit and Allen wrench.
Note on case compatibility:
This model is intended to fit the Hero5/Hero6 dive housing and will also fit the Hero5/Hero6 frame. This model will also fit the Hero3/Hero4 but only if using the slimline housing.
