The Dahle 20394 has a 16” feed opening and is driven by a powerful 2 hp motor. A solid steel frame houses and aligns two perfectly matched cutting cylinders milled from a single bar of German Solingen steel. It’s this design that maximizes durability and minimizes flexing to produce a consistently fine 1mm x 4.7mm particle size. This High Security Shredder uses the latest technology to offer full electronic capabilities including such safety features as Automatic Shutoff when the cabinet door opens and Auto Reverse to prevent an overfeed. Automatic On⁄Off and Bag Full Auto Off are features that offer both convenience and satisfaction in knowing you will be notified when it’s time to empty the box or change the bag. This rather stout machine is housed in a wooden cabinet with casters making it easy to move and position in its place of operation.
