Our 1-1/4” diameter washers are available in two styles. The washer with tabs (part number ET-90) is used over soft material such as insulation for added grip. The flat washer (part number EF-90) is used with hard material like gypsum board. Both washers can be ordered in combination with our AKN-100 series pins for use with the Model 500M tool.


Our 1-3/4” plastic washers are available with or without stems. For use with soft materials like insulation, order the EP3 washer. Order the EP4 washer without stem if a flat plastic washer is needed for use over hard face materials like gypsum board. A Model 500M tool with a washer holder for these plastic washers is available. (Plastic washers are a non-stock items, available by special order)
