Abstract: A vibration dampening device is of two-piece construction with each piece having an outer plastic backing sheet for a layer of vibration dampening foam material secured to the inner surface of the backing sheet. A layer of pressure sensitive adhesive material is disposed on the inner surface of the vibration dampening foam material, such adhesive material being initially covered by a protective tape. The protective tape is pulled off of the adhesive material of each of such pieces and the two pieces aligned vertically over adjacent strings on either side of the racquet. Thereafter, the two pieces are pressed tightly towards each other to cause the pressure-sensitive adhesive material to adhere together and thereby anchor the two pieces as an integral unit upon the strings.
