The Black Swamp Professional Castanet Mounting Frame is an easy way to convert handheld castanets into a machine-style mounted instrument. It's made out of aluminum, which means it's strong without being too heavy, and it has two rubber-lipped holes that allow for two handheld castanet handles to be inserted.
This stand will not mount castanets with no handle, and it is designed specifically for castanets which are already mounted to handheld handles for easy performance.
