The PATENTED and award-winning MS-526 Mid Span Slit and Ring Tool is designed to provide easy access to optical fibers in Corning Altos loose tube�cable with binderless FastAcess technology (as well as other similar thin-walled 9.8 to 18.2 mm diameter jackets). Building on the popularity of the Jonard Tools MS-6 and MS-26 Fiber Optic Mid Span Slitting Tools, we have incorporated a ring feature in the tool to make it even more versatile.
