Set of two PowerAngle black, diamond vibration dampeners. These are replacements, as each purchased racket includes a set of two vibration dampeners.
PowerAngle recommends using two PowerAngle vibration dampeners, which must be inserted outside of the woven area.
After stringing is complete, insert the two vibration dampeners above the diamond logos on the inside of the bottom of the hoop. Turn each vibration dampener 90 degrees to lock in place.
