This tool automatically sets flangeless wipers to their proper depth in the seal head. This tool uses a special extension or "bushing pilot" at each end that enters the lower assembly and interfaces with the bushings the same way your fork's stanchion tubes do. This results in perfect alignment of the wipers before they are pressed in. It is simply impossible to get the wipers "cocked" at an angle when installing with this tool.
