The AD-E2 holder for Godox AD100Pro, AD200Pro and AD300Pro is stable and sturdy. It has a universal 1/4 inch screw, so you can mount lamps from the AD family or other compatible units on light stands.
With three locking knobs, you can set any angle of the lamp, and the mount itself has a hole for a photographic umbrella.
The holder uses a mounting system that guarantees stability between the flash and the light stand.
