Our DP500 Tab Washer is a galvanized, 1-1/4-inch plate used for stucco applications. It has metal tabs that hold and lock stucco sheathing in place, reducing washer spin. Each washer comes with a G90 plating that resists corrosion from weather exposure. Prolonged corrosion, especially in coastal areas, mandates covering the DP500 with a stucco base within a few hours of installation to prevent unnecessary exposure
