Micro Jig's MDC-17 Magnetic Dust Cover is designed to cover the bevel slot of your steel table saw. Significantly improve your dust collection by sealing the bevel slot opening in your table saw to generate greater suction concentration and eliminate the possibility of dust gathering inside the opening. Use when making 90-degree vertical cuts. Can be cut to fit most steel cabinet table saws. Prevent airborne saw dust from getting out of control and enjoy cleaner ripping and cross-cutting on your table saw.
