The Quick Change Cymbal Mounting Kit from Gibraltar 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 by attaching 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 which allows the player to attach an upper hi-hat cymbal easily, without the locking nut unthreading during play.
