The JLH-DC001 Drop Clutch was designed to work with Roland VH-11, VH-12, and VH-13 series of electronic Hi-Hats. It comes complete with lever/latch mechanism and the custom JLH Clutch Holder Guide assembly which is made in the USA. The unique design of the guide assembly allows the lever/latch mechanism to work as intended while also keeping the cymbal from spinning. It is crucial when playing electronic hi-hats that you maintain the position on the striking edge of the cymbal. This is the perfect device for drummers that play double bass.
