Abstract: The present invention is an inline ball valve shutoff tool for moving an inline ball valve handle used to open and close inline ball valves. The tool allows access to inline ball valves that are difficult to reach due to obstructions and height restrictions. The tool allows for access through the maze of conduits and other obstructions which block access to inline ball valves. There are approximately eighteen different sizes of pipe commonly used for supply lines and all require different sized inline ball valves and valves handles. Generally pipe lines run in either a horizontal or vertical direction. For pipes running in the vertical direction, the inline ball valve handles operate in a vertical plane. For pipes running in the horizontal direction, the inline ball valve handles can operate in either the vertical plane or a horizontal plane. The different components of the inline ball valve tool allows for movement of different sized valve handles that are in any of the positions described above.
