Can multiple tracks be used to extend cut to more than 48"?

The Accu-Cut is designed for 48" of maximum cut capacity. Kreg offers a product called the Rip Cut for making longer cuts by referencing the edge of the material being cut for an offset distance and guiding the saw parallel to that edge.You may also want to consider the True Trac kit which offers an alternative solution.While all of these will produce reasonably good results, the best results can be achieved with a track saw designed for this application. We offer track saws in a variety of price ranges from multiple manufacturers: Festool, Dewalt, Makita, Triton and Mafell.
