The Jonard MS-326 Mid Span Slit and Ring Tool is designed to provide easy access to optical fibers in thin-walled outer 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. Consists of 5 precision slitting grooves and 5 precision ring grooves ranging in size from 5 mm to 10 mm One side of the tool performs radial/ring cuts, and the other side slits the cable (longitudinal cut) The compact design, weighing less than 2.5 oz with an included tethering hole, makes it perfect to use in tight spaces or on the go The indicator line on top of the unit indicates the blade's position for accurate slitting and ringing. This tool was specially designed for use on Corning fiber cables such as MiniXtend® binderless FastAccess®, HD MiniXtend®, and other similar-style cables Replacement blade set available, part number: MSB-5010 Blades last for 5,000 slits/cuts The Jonard MS Series Mid Span Tools are patented for their unique design and functionality.
