Compact stapler features a patented spring-powered mechanism that delivers 25 lb. of power with only 5.2 lb. of effort. It staples up to 15 sheets with the press of a single finger, the equivalent of pushing an elevator button. Set up horizontally with a small footprint or vertically to save space. Stapler offers jam-free performance, a comfortable ergonomic grip, handy staples-remaining window, and easy drop-in loading of standard staples. It opens for tacking and includes a half-strip of staples.
