Festool 495209 Guide Rail Splinter Guard, 197 in. Festool FS Guide Rails come in a variety of lengths from 32 inches up to 197 inches, designed to provide the length for straight, splinter- cutting in nearly any project. The integrated splinter guard is an essential part of the guide rail system, protecting your cuts from tear out and ensuring precise alignment with the cut line. Over time and with heavy use, the splinter guard will need to be replaced to maintain optimal performance. Regularly changing your splinter guard is especially important if you switch between different blades or use the guide rail with multiple saws, as it helps save valuable setup time and keeps your cuts clean and accurate. The clear splinter guard enhances visibility of the cut line, making it easier to achieve results every time. This product includes one 197-inch (5000mm) clear splinter guard, designed to match your saw blade precisely for superior protection and cuts both with and across the grain. Model Number: 495209
