Festool 201183 Parallel Guide Extensions, Imperial lets you cut sheet materials on site with precision, eliminating the need to transport them back and forth to a table saw. This extension attaches to Festool's Parallel Guide to enable very narrow, repetitive cuts, accommodating material widths from as narrow as 1/16" up to 7-11/16" (195mm). Designed to accept the same stops as the Parallel Guide, it must be used together with the Parallel Guide and is compatible with any Festool FS/2 Guide Rail (guide rails sold separately). Made in Germany, this system provides a convenient and accurate solution for on-site cutting needs. Model Number: 201183
