The MEINL X-Hat Auxiliary Hi Hat Arm keeps a pair of hi hat or stack cymbals in a stationary position anywhere on a drum set up. The clamp and boom arm make it easy to attach and position at any height or angle. The tension adjustment makes it possible to finely adjust the amount of pressure on the cymbals from very loose for an open, sizzling wash, to tight and crisp with a strong chick sound. The cymbals are not included. The arm measures 14".
