The Gibraltar Swing Nut Rocket Adapter allows you take a cymbal off of any cymbal stand with a flick of the wrist! The sleeve, tension spring, and wingnut all come as a single unit - just screw it onto any 8mm tilter, push it down to release the swing nut, put the cymbal on the stand, and flick the swing nut back into the locked horizontal position. It takes a second, and you'll never have to worry about missing wingnuts again.
