Festool 491582 Limit Stop for Guide Rail is designed to provide secure stop points for repetitive cutting and routing with most Festool routers. It affixes easily to the rib or guide on top of the Festool FS Guide Rail, ensuring precise and consistent results. This limit stop fits seamlessly to the rear of the TS plunge cut saw's sole plate, helping to reduce the risk of kickbacks during plunge cut starts. While Festool TS saws come with a single Limit Stop, having a second stop is beneficial for pairing as a stop or start point. This product includes one Limit Stop that fits quickly and securely to the top of the FS Guide Rail for both cutting and routing applications, ing a reliable and positive stop for starting or ending a cut.
