The GCN-MEPMAGKT gas-actuated concrete nailer is a portable fastener tool for attaching light-duty fixtures to concrete, steel, concrete block (CMU), lightweight concrete over metal deck, and cold-formed steel. As a magazine tool, GCN-MEPMAGKT is ideal for attaching drywall track, furring strips, hat track and angle track using GDP and GDPS collated pins. Offers you the flexibility of having two tools in one convenient package — a magazine tool and a single-shot tool, since the magazine is easily removed without additional assembly tools. As a single-shot tool, the GCN-MEPMAGKT is great for attaching mechanical, electrical and plumbing fixtures with pre-assembled pins/accessories such as washer pins, ceiling clips, top hats and threaded studs. The pre-assembled pins for the single-shot tool use 0.300″-headed fasteners with 0.125″-diameter shanks for stronger fastening performance. Both the single-shot and magazine tool offer portability without the need for cords or hoses and are actuated with GFC34 gas fuel cells.
