The Noga AD4000 Quick-Release Adapter with M6 Thread is a pull-to-release adapter that replaces the standard 1/4”-20 thread mount on the top of all Cine Arms Series arms. It allows for quick and easy mounting and release of accessories on the Cine Arms. It utilizes a 1/4” male thread with non-slip rubber surface for mounting accessories like monitors, lights, etc. You can then mount the preloaded accessory to the arm by pulling back the release sleeve on the adapter and inserting in the accessory.
