The Wilson Shock Trap Clear Dampener is the ultimate vibration dampener. It dampens the amount of vibration that reaches your arm and reduces the risk of tennis elbow. It is wider in the middle to reduce shock and vibration where most balls are hit. It contacts multiple main strings to absorb the shock produced on the frame and strings on impact. This shock trap provides more comfort while playing. It is stylish clear with the Logo "W" and a very lightweight dampener. It is a great dampener that fits into any racquet string bed to provide maximum shock absorption.
