The large hook wraps around the shock body. You thread the main stem up against the shock body and insert the allen wrench. Then you use the large black wing nut on the back of the tool to unthread the allen plug allowing you to fill the shock. Once you've filled the shock, you then thread the allen plug back into the shock body and disconnect the tool.
