The patented MS-326 Fiber Optic Mid Span Slit and Ring Tool is designed to provide easy access into fiber optic cables specifically used in micro ducts. These cables have a thin wall jacket design that is difficult to open without causing damage to the buffer tubes inside, but the MS-326 addresses that concern. The MS-326 will also slit thin wall buffer tubes. 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.

The MS-326 consists of 5 precision slitting grooves and 5 ring grooves ranging in size from 5 mm to 10 mm.

Groove Sizes: 5.0 - 5.6 mm | 6.0 - 6.6 mm | 7.2 - 7.8 mm | 7.8 - 8.4 mm | 9.4 - 10 mm


  1. Identify the correct side of the tool & groove size for your cable.
  2. Place cable in the tool and close to lock in place.
    • To Ring: Rotate 3-6 times in direction of arrow
    • To Slit: Pull in direction of arrow
  3. Open tool and remove cable. If slit, peel open the jacket along slit lines.

Note: This tool was designed for Corning fiber cables, "MiniXtend Fast Access Binderless" and "HD MiniXtend" as well as other similar styles.
