DW Cymbal Stackers' thread fits any DW cymbal stand to create multi-cymbal and percussion effects setups. The Stacker eliminates the need for another cymbal stand or a bulky arm. This DW stacker is 6" long, which makes it ideal for smaller to mid-size cymbals such as splashes, crashes, or Chinas. Helpful Hint: Place a smaller diameter cymbal on the stacker and a larger one on a cymbal stand. Now the DW Cymbal Stacker has made both cymbals easier to play.6" tall Threads onto any DW cymbal stand Small and easy to install
