Minimum Cleaning Required
The GCN-MEP has a very efficient ignition system that provides complete fuel
combustion. This results in a cleaner operating tool which, in turn, results
in more tool energy and higher productivity. To maintain maximum level of
productivity, periodic cleaning is recommended.
 • Only requires cleaning every 20,000 shots
 • Easy access to the air filter and piston chamber
• Conduit clips
• Ceiling clips
• Low-voltage cable
• Cable straps
• Drywall track to concrete, steel, CMU
or lightweight concrete on metal deck
with magazine
The GCN-MEP Gas-Actuated Concrete Nailer is ideal for fastening:
