The Nemco 57424-7 1/2 in slice blade and holder assembly is a replacement part for the Nemco Easy Chopper 3™. Purchasing the right part for your Nemco Easy Chopper 3™ is easier than ever with the new color-coded system—simply match the color of your blade assembly with your push block and you are good to go! Not only that, replacing your blade assembly just got easier (and faster) now that these parts are completely separate from the guide rods—no need to remove those bumpers!
