Pacific Drums & Percussion's PDAXMGQ6G is a Quick Grip Cymbal Boom Arm with an MG3 tube to boom arm clamp.  The MG3 clamp allows you to attach this cymbal boom arm to any cymbal or drum stand in order to place small cymbals into tight areas or as a way to expand the number of cymbals in your kit without needing to purchase and place an entirely separate cymbal stand around your drums.  Works best with cymbals under 16" such as splashes and bells.
