The splinter guard reduces tearing when sawing. The adhesive coating provides a secure, non-slip grip and protects the surface of the workpiece. It features holes for attaching the rail to the workpiece and for hanging storage. The rail can be extended with a second guide rail using the FSV connector. It is compatible with many hand-held circular saws from other manufacturers that are suitable for use with rails, including Hikoki, Festool, Bosch, Makita, Hilti, and others. It is also suitable for Metabo hand-held circular saws.
