Cutting wood with accuracy is an important part of making sure the project turns out just right. The inaccuracy of pencil marks on a board can then be compounded by the need to follow that mark precisely with the saw blade. The Kreg Precision Trak and Stop Kit is designed to take the guesswork out of cutting wood to length. This kit contains 8 (4 x 2 sections) of anodized aluminum trak that can be mounted to a shop made support wing built to the height of your miter saw. A ½ inch self-adhesive tape is then applied to the top of the fence. Finally, slide the Flipstop and Production Stop onto the top of the trak and you have a precision cutting station that eliminates the need for a tape measure and pencil. Simply place the precision lens cursor over the board length desired, press the board against the stop, and cut away! Precise, repeatable cuts could not be any easier.
