Gardner Bender provides a complete line of staple and fastening solutions for all industries, including industrial, residential, construction or manufacturing. From low voltage wire to service entrance cables, professionals rely on Gardner Bender for quality fastening products. Gardner Bender's standard and most popular staple used to secure NM (non-metallic) cable.

Gardner Bender's 1/2 in. metal staples are preferred in the industry as they are slightly longer than competing models, which improves holding strength and makes them easier to grab.

      Very low grade metal
      Not usable. Metal is too soft. Of the first ten (10) I used, one (1) went in straight. Five bent up like pretzels but good enough to hold the wire, and four had to be pulled because they were useless. Returning the whole thing - the extra trip will be less work than getting staples made of better metal.
