Klein Tools' Cable Stapler drives insulated staples for Romex® and data cables with one hand. It features a forward action handle for greater stability, which allows user to push the handle, rather than squeeze, delivering easy, consistent performance. Staples are released from the front of stapler, nearest to where the handle is pressed down. A cable guide along the entire bottom surface protects the cable during the stapling process. Use only with Klein staples (sold separately).
