Compact, lightweight, heavy-duty stapler is made using recycled plastic and fastens up to 80 sheets. The leverage mechanism is optimized for high-capacity stapling, requiring less effort to use while providing a jam-free operation. Rubber base provides stability, and an adjustable throat allows deep stapling. Stapler uses any 1/4" , 3/8" and 1/2" heavy-duty staples (sold separately).
