Imagine being able to cut sheet materials - on site - to very accurate specifications - without lugging it back and forth to a table saw. Festool's Imperial (fractional) Parallel Guide & Extension System makes possible exactly that. The Parallel Side Fence (#201182) attaches to the Guide Rail and holds it at precise settings for highly accurate and repeatable cross and rip cuts. 2 adjustable stops engage the edge and keep it parallel to the cut. It is adjustable to cut stock from 5-1/2" to 25-19/32" (650mm) wide. The Parallel Guide Extension (#201183) attaches to the Parallel Guide (#201182) to make very narrow, repetitive cuts. It accepts the same stops as the Parallel Guide, and will cut material from as narrow as 1/16" up to 7-11/16" (195mm) wide. Extension must be used with the Parallel Side Fence. System works with any Festool FS/2 Guide Rail. Guide rails sold separately. Germany
