The EH-70F II Electronic Stapler lets you staple 2 to 70 sheets at the speed of two staples per second without changing the staple. It generates professional-quality stapling with the Flat Clinch Mechanism so staple close flat and papers stack neatly and evenly. Flat Clinch bends the staple ends flat without deforming the clinched staple. Quiet motor-driven mechanism means you avoid disrupting work while you staple. Designed for heavy-duty commercial and office use, stapler gives you the option of auto or manual stapling for perfect positioning of staple every time. Auto throat depth ranges from 1/4" to 3/4". Manual throat depth is 1/8" to 3/4". Metal finger guard restricts access to the stapling mechanism to improve safety. Four-point rubber grip helps stabilize the stapler. Heavy-duty stapler includes easy snap-in cartridge for its maximum load of 5,000 staples so you can staple 5,000 times continuously. It uses the Max 70FE II staples that have a 1/2" crown and 5/16" leg length.
