SKU-54562272
                        Made especially for stripping 8mm & 8.65mm Moroso ignition wire and others.
  • An easy way to strip wire without damage, which is more likely to occur using other methods
  • Simple and efficient operation: place the end of the wire in the “mouth” of the tool, twist in a circular pattern until the cut is made around the wire, then pull off sheath
  • Heavy-duty construction and quality components provide relaible operation after repeated use
  • After using this Enhanced Stripping Tool, you will never go back to using manual strippers for assembling wire sets again
