Now for THHN and THHW industrial insulations. the original Stripax set the industry standard for precision stripping for a decade. the new Stripax Pro 6 and Pro 16 perform powerful stripping of standard and industrial insulations for a wire range of 28 to 10 AWG (0.08 to 6 mm2) and 10 to 6 AWG (6 to 16 mm2) respectively. the ergonomically designed, contoured handles let you hold the tool in a natural position so stripping is comfortable and requires less effort.
