Spire 4″ extensions are intended for cues and players that need just a slight increase in length for those winning shots. The 4oz extension piece leavesthe the feel of the overall cue the same a before due to the weight being just the right amount of end weight. This Spire 4 inch butt end extension has three different adaptors to fit some of the popular cues such as Predator, Mezz, How, and Fury.

To use, take the butt bumper out of your cue, attach the properly fit adaptor, then take the extension and twist it into the newly placed adaptor. With an adaptor at the end of the extension, you could also stack another extension if needed.
