Overview
The Jonard Tools MS-446 is a precision-engineered mid-span slitting and ringing tool designed for efficient fiber optic cable access. It is specifically optimized for AFL's Heavy Duty OSP MicroCore (LMHD-Series) cables and other thick-walled cables with outer diameters ranging from 8.7 mm to 14.6 mm. The tool provides a clean, precise cut to remove cable jackets without damaging the internal buffer tubes.
Constructed for field use, this tool features four precision slitting grooves and four ringing grooves, clearly marked by cable size. The integrated blade design supports both longitudinal slitting and radial ringing, making it an essential instrument for technicians performing mid-span access in challenging OSP environments. Its compact, lightweight housing includes a tethering hole for safety and convenience in tight spaces.
