The Jonard Tools Mid Span Slit & Ring Tool for cables from 1.2 to 3.3mm is designed to provide easy access to optical fibers in outer jackets and buffer tubes. It consists of six precision slitting grooves and six precision ring grooves ranging in size from 1.2 to 3.3mm. One side of the tool performs radial/ring cuts and the other side slits the cable (longitudinal cut). The indicator line on top of the unit indicates the position of the blade for accurate slitting and ringing.
