The Parallel Guide System greatly enhances the capability of the Festool Guide Rail System by providing a faster, easier, smarter way to create consistent rip cuts. The Parallel Guide Set is comprised of the Parallel Guides and Parallel Guide Extensions and offers savings versus purchasing these two products separately. The Parallel Guides are the longer sections and offer consistent rip cuts up to 650mm (25 19/32 in) using two adjustable stops that engage the edge of the material parallel to the cut line. The Extension allows you to make narrow repetitive rip cuts ranging from 1mm to 195mm (1/16 to 7 11/16). The Extensions must be used in conjunction with the Parallel Guide. The Parallel Guide can be used with any length Festool FS/2 guide rail. Guide rail sold separately. Made in Germany.
