There are a number of similar cable slit and ring tools on the market, but not one like the CSR-1575 Cable Slit & Ring Tool because this one tool replaces two similar tools most technicians use currently for larger and smaller cables. With the removable reversible V block, the CSR-1575 accommodates both smaller and larger diameter cables. The CSR-1575 is designed to slit and ring UTP, STP, Coax, SO, SJ, SJT, RG58, RG174, RG187 and other cables, plus buffer tubes and jackets on fiber optic cables up to 7.5mm (0.3") in diameter. Besides measuring just 4-1/2" this tool features a convenient finger ring opening on the end of the tool for ease of use. The adjustable slit blade and the ring blade can be set for any depth to insure nick-free strips and slits. Replacement blade are available…just request the CSR-2 Replacement Blade Set.
