The Metabo 80mm Guide Rail (FS80) transforms a regular circular saw into a precision cutting tool, allowing for straight and reliable guidance when cutting sheet stock. Its non-slip coating securely holds the guide rail in place while simultaneously protecting the workpiece surface from damage. The overall length of the guide rail is 31.5” (80 cm), which can be extended by connecting multiple guide rails with the FSV Connector (sold separately). The FS 80 guide rail is also compatible with circular saw guide rail systems from other manufacturers.
