These rubbers have side profiles and are specifically made to work with the pumping rosettes. They can also be used to reduce amplitude with the higher count pumping rosettes as well. It comes as a set of four with two different radii each one. The one side of each allows for the creation of a sine wave pattern on the respective rosette.
