The CCM Composite End Plugs add 4" of extension to your hockey stick or shaft and are built with a featherlight carbon fiber composite. This composite barely adds any weight to your stick and helps to keep your balance point true and precise. The R plug is built to fit Senior sticks from CCM's JetSpeed, Tacks, and RibCor families while the I plug is designed for Intermediate CCM sticks from all three families.
