Sonor BA19-M MC Basic Arm 19 220mm

I use it for an 8" closed hi-hat stack mounted on a cymbal stand in combination with a couple of other Sonor clamps and the Sonor remote X-Hat holder. It provides a lot of options for positioning a small diameter hi-hat around a kit and from personal experience is more flexible than a dedicated x-hat holder (e.g., Meinl and DW I tried were great and sturdy but somewhat limited in terms of positioning).
