Just rotate the adapter ring clockwise to lock any inserted accessory, or counter-clockwise to release the accessory. Innovative design ensures that you get a very solid hold and the accessory is perfectly centered every time. No thumbscrews to worry about! The internal ball bearings and detents make this adapter a joy to use.
