Booklet staplers are staplers with a long reach that allows the placing of staples in the spine of a booklet. Some booklet staplers rotate 90 degrees to allow for both horizontal and vertical stapling.
A saddle stapler is a version of a booklet stapler that contains a V-shaped anvil. The stapler is designed specifically for proper placement of booklets papers. It is often operated by a foot pedal for easier handling of the papers during the process. Long-reach staplers stretch across up to 12 inches of paper at once in order to create booklets with up to 25 pieces of paper at a time.
