I found this piece with some other drum gear, and wasn't quite sure what it's for. The diameter of the clamp is too small to mount to pretty much any stand without affecting the disengage lever (in the middle). There aren't any labels, brands or markings on it other than "patent pending" and "USA / 7"
Does anyone recognize this piece or know what's its use is? I'm sure it's something simple, but I can't seem to figure it out :)
