The QuikFit® system is quick and affordable solution to custom clubfitting. The purpose is for fitting only (and not play) as a way to interchange heads with different shafts in order to find the right combination a customer might need. Select drivers and 6-irons are especially bored to accept the QuikFit® adapter. Each Quikfit head comes with one adapter (extra adapters sold separately). Note the QuikFit® adapters will not fit any other brand of clubs on the market.
