This custom knob slips over the stock Sea and Sea focus knob to allow easier control and a much better grip. Divers that wear gloves will love this better grip!!! It also comes with an extension piece and a bolt that slips between the stock handle and the housing. This allows the knob to fit properly between the housing and handle.
