Abstract
Apparatus for fitting a golf club to an individual player comprises a plurality of shaft extension plugs that fit into the upper end of a club shaft so as to provide various effective shaft lengths. A removable elastomeric grip, configured as a tube having a closed end and a slit extending from the open end to a point near the closed end, is slid over the shaft and whatever extension plug is inserted into it. The inner diameter of grip is matched to the outer diameter of the shaft, and the inner surface of the grip is smooth. This arrangement provides a maximum contact area between the grip and the shaft in order to keep the shaft fro sliding out the grip when the player swings the try-club. One of the advantages of this arrangement is that it reduces the number of individual items of equipment that a fitting dealer needs to stock in order to cover a full range of performance parameters.
