Tired of your cello skating away while you’re playing? This inexpensive solution anchors your cello endpin securely and lets you focus on the music. It’s adjustable, lightweight, and folds easily for compact storage in your cello case or gear bag. Older products like “rock stop” rubber discs and rubber endpin caps fail and slide away on dusty floors or outdoor surfaces. Put one of your chair’s front legs into this strap’s metal ring and your cello endpin in the cup, and your cello won’t run off again.
