Product Overview: 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. Features: The special design of this Grip Installer Tool makes grip installation on popular big butt graphite shafts a breeze.
