Made from durable rubber, it sits securely across the bottom strings with a simple slit-in design that installs in seconds without tools. As a wilson vibration dampener, it fits most tennis rackets and stays put through play, softening the shock and vibration felt at contact. Ideal for players of all levels who want a cleaner feel with a bit of US Open style.
