<p>A throat piece for a tennis racquet has a series of indentations which provide parallel ridges and depressions on its two major faces. The ridges on one face constitute the depressions on the other face. The longitudinal racquet strings pass across the throatpiece in contact with the wall of the indentations and are diverted thereby into the racquet frame. Preferably alternate strings pass on opposite faces of the throatpiece but in the same plane. The structure is preferably of crenellated shape and may be of metal or plastics material.</p> |
