With its patented (US.Pat. 9355625) Quick Pinch-and-Release function, the Pearl Rapid Lock Hi-Hat Drop Clutch is the fast set-up/tear-down solution every gigging drummer has been waiting for. Easily pinch both sides of the bottom locking nut to release and place the top hi-hat cymbals and adjust the cymbal feel with the locking top adjustment nut. The drop clutch function quickly releases the top cymbal for closed hat play in double-bass drumming and reattaches with a quick kick of the hi-hat pedal.
