Novus - DAH0201535 High-performance stapler features an extra-long throat depth for saddle-stitching booklets. Dual-staple guide system provides excellent performance and ensures each leg of the staple has even pressure until it clinches your documents. Dual mode stapling produces either a permanent standard clinch or temporary pin. Temporary pin mode allows you to easily remove the staple from the back of the document without any other device. This eliminates the need for paper clips or other temporary fasteners. Each mode is easily attained by rotating the circular anvil at the base of the stapler. Anti-blocking system prevents internal jams from occurring for hassle-free performance. Adjustable-depth guide has inch and metric scales and ensures you staple at the desired depth each and every time.
