The Quick Change Cymbal Mounting Kit comes with three Quick Release Cymbal Locks and one Quick Release Hi Hat Clutch. The quick release function was designed to be an effortless change for cymbals and hi hats with rock solid performance. The Quick Release Cymbal Lock attaches to the cymbal post with the push of a button, allowing the player to fine tune with extra threading. The Quick Release Hi Hat Clutch uses a ball bearing sleeve locking mechanism. This allows the player to attach an upper hi hat cymbal easily, without the locking nut unthreading during play.
