Unscrewing a typical clutch from the top hi hat cymbal is a pain when you're trying to set up or tear down. Pearl's Rapid Lock Hi Hat Drop Clutch reduces this tedious little process to a few seconds!
Squeeze the two silver "triggers" and the bottom of the trigger will simply pull off or push on with no unscrewing. Release them and they'll lock into place.
The red locking nut applies downward pressure to make sure it doesn't loosen up over time. You can further strengthen the locking nut's position by tightening it down with a small allen wrench.
This drop clutch is made for double bass drummers - smack the black lever at the top with your stick and it will force the hats together so you can move your foot to the slave bass pedal and still get a closed hi hat sound. Put your foot back down on the hi hat pedal and it will unlock.
