Slide Stopper (Trumpet) YAC 1360P
The Yamaha trumpet slide stopper is designed to prevent the 1st and 3rd slides from slipping while playing. The silicon rubber material is strong and durable, and won't damage your instrument's finish. In addition, it's springy and elastic, allowing you to use both slides during a performance with the stopper still attached.
The colors and finishes shown may vary from those on the actual products.
