The special design of this Golfsmith Grip Installer Tool makes grip installation on popular big butt graphite shafts a breeze. While it is recommended for grip installation on oversize butt shafts such as .865" and .700", it also works great on conventional shafts and grips. Simply slide a lubricated slip-on grip over the nozzle and slip the whole assembly over the shaft butt. The tool then slides down the shaft and off.
