Abstract: A fence for a radial arm saw used as a dado cutter or molding cutter with the cutting head in a horizontal orientation is disclosed. The fence provides a work surface perpendicular to the saw table surface and includes two fence panels having a thickened lower area for being clamped in the fence slot of the saw table and an adjustable gate panel positioned between the fence panels. An aperture is formed in the gate panel for admitting a work-performing portion of the cutting head. The gate panel is capable of accommodating the various heights of the cutting head by moving between a lower position where the aperture is adjacent to the surface of the saw table and upper position where the aperture is above the table surface. The gate is appropriately secured with the aperture in the desired position for the height of the cutting head. The thickened areas of the fence panels provide clearance for the gate panel to move into the fence slot so that the aperture may be positioned adjacent to the saw table.
