Festool FS Guide rails are available in eight different lengths from 32 inches to 197 inches (800 - 5000 mm), providing the right rail for every application. The integrated splinter guard aligns perfectly to your cut line, saving set up time and serving as protection against tear out, on cuts both with the grain and across. Guide rails can be easily connected using the accessory guide rail connectors(sold seperate) for a rigid, secure and continuous connection. Guide rails make work easier by taking the tool to the work, and save time and money by eliminating laborious measurements, rework and wasted material.
