Abstract: A variably compressible device placed on the peripheral portion of a racquet frame over or through which a loop of racquet string is placed compressing and holding the device against the outside surface of the racquet frame. The device and method provides for a controlled degree of compressibility permitting selected strings to undergo greater deflection through processes of device compression and intrinsic string elongation when striking the ball compared to the behavior of an equivalent string striking the ball without the device.
