It offers reduced jams thanks to a specialized inner rail, and staples up to 20 sheets at a time. The metal stapler is durable and designed for quality stapling from a desk or countertop. A positive locking latch makes sure staples are in proper position for seamless use. The stapler opens for tacking to post papers to a bulletin board or other vertical surface. Its anvil also rotates for a pinning function to create temporary staples. A low-staple indicator on the side of the magazine makes it easy to identify when staples have run out. The stapler holds a full strip of 210 staples. Recommended for use with Swingline S.F. 4 Premium Staples, 1/4" Length for best performance.
