Designed to slit and ring fiber optic cables from 0 to 0.125" in diameter, this CSR-125 Compact Cable Slit & Ring Tool from Jonard Tools is ideal for slitting and ringing cables, buffer tubes, and jackets on fiber optic cables. Use this tool on fiber, coaxial, and electrical cables with the same diameters as RG-174 or RG-187 cable. Designed to cut only the jacket, this cable slit and ring tool speeds up cable assembly compared to working with a knife blade. It includes two cutting blades and one rounded blade for slitting without damaging the inner conductors.
