Wilson's Tungsten Tuning Tape is perfect for players that want to customize their racquet for a specific weight or balance. Each full strip weighs 2.5 grams (0.25 grams in each section). Depending on the positioning of the tape, players can add weight for stability, power or to increase maneuverability. Adding weight at 3, 6, 9 or 12 o'clock, in the throat, or on the handle can significantly alter your racquet to your very own specifications. It is recommended that you take care when adding weight to your racquet and make sure to add weight evenly to both sides in order to keep your racquet consistent.
