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 8 mm 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.
