Take the guesswork out of cutting wood to length with Kreg's Precision Trak and Stop Kit (KMS8000). Perfect for setting up a measuring system for your miter saw, radial arm saw or drill press, it enables you to make precise, repeatable cuts to boards exactly to length. It helps prevent measuring or cutting errors and eliminates the need for tape measure and pencil. Just place the precision lens cursor over the desired board length, press the board against the stop and cut. It includes 8' of anondized aluminum track, measuring tapes, flip and production stops, and detailed plans for building miter saw wings from melamine.
