For the majority of racquets, you will use either 3 or 4 Pojies, one for each pair of strings at the bottom of the throat of your frame. If you have 8 strings – 4 string pairs – at the throat, you use 4 Pojies. If there are 6 strings (3 pair) coming into the throat, you use 3 Pojies.
However, a few racquets do not easily accommodate 4 Pojies, even though they have 8 strings (4 string pairs) coming into the throat area. With these frames, the outside Pojies will be angled into the yoke of the racquet and the string itself will likely be in contact with the frame after stringing. In this instance, we recommend that you only use 2 Pojies. The Head Graphene Prestige S, Prince Tour ESP 98 & Tour ESP 100, Mantis Pro 295 and Volkl VI MP (102) are examples of this.
Other frames where the clearance is very tight include the Dunlop M4.0, Babolat Pure Control and Head Graphene Radical S. Depending on the string tension you use, you may have enough space between outer Pojies and these frames that the string does not touch the racquet.
