Our Precision Trak and Stop Kit allows you to turn a miter saw into a precise cutting system - without the need to use a tape measure or a pencil. You build the support wings out of plywood (or another sheet material) with the right height fitting your miter saw. As back stop it is best to use a 57 mm high ledge to attache the traks to. The 4 aluminum profiles with 610mm each allow fa flexible setup - 2440mm on one side, 1220 mm on either side or 1830 mm on one side and 610 mm on the opposite. The included Swing Stop™ and Production Stop ensure accurat, repeatable cuts.
