Before you build

This is a club-building component, not a ready-to-play club or an adapter-installed replacement. Have your club builder confirm tip/hosel compatibility and follow the manufacturer’s trimming instructions before installation. Raw length and tip diameter have not been verified for this inventory; please confirm these details before purchasing if your build requires a specific size.
