This clamp is designed specifically for the Feiyu-Tech G3 Ultra Hand Held gimbal. It encapsulated the handle holding it firmly in place without risk of it falling out.
Fitment is super simple and only involves popping one of the nuts from a standard GoPro mount bracket out and placing it into the clamp (see video
This is for the G3 Ultra and will NOT fit the G4. The G4 Clamp can be found here:

PLEASE NOTE - THE NUT AND BOLT ARE NOT INCLUDED.... but if you own a GoPro you will have them both anyway!
