Meet the King! Superior to all our heavy duty staplers is the Auto180 Xtreme Duty Automatic Stapler that can staple a profound 180 sheets with just ONE staple size! Skillfully, this stapler automatically trims the staple to the precise size for a customized fit to each job at hand. To generate a professional look and facilitate neater stacking every time we built in a flat clinch system. No more agonizing over staple jams that hinder your productivity because we have integrated the Anti-jam technology for convenience. For your optimal stapling comfort, we have fabricated an ergonomic handle and to guarantee durability and quality it's constructed of metal composite. Pushing the boundaries to allow you to personalize the reach of the staple is the adjustable paper stop. Extra reinforcement is needed with extreme duty jobs so we applied a full rubber base pad to keep the stapler in place at all times. Uses Staples SB38HD. 7 year warranty.
