New Tech Mach II Geared Shears are mechanically advantaged forward pulling shears for cutting 5" & 6" gutter to length. The shear acts as a guillotine, providing a clean and precise cut compared to trimming with hand snips or saws. When you have reached the desired length of your gutter, simply stop the machine and easily pull the lever of the guillotine towards you to release it, then remove the finished gutter section.
