G3 Gas-Actuated Fastening Tool

The G3 gas-actuated fastening tool 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, G3 is ideal for attaching drywall track, furring strips, hat track and angle track using GDP and GDPS collated pins.

G3 offers you the flexibility of having two tools in one convenient package — a magazine tool that easily converts to a single-shot tool. As a single-shot tool, the G3 is great for attaching mechanical, electrical and plumbing fixtures with preassembled pins/accessories such as washer pins, ceiling clips, tophats and threaded studs. The preassembled pins for the single-shot tool use 0.283"-headed fasteners with 0.126"-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.

Key Features

  • Depth of Drive control switch for pin depth adjustment
  • Battery charge indicator lights
  • Comfortable “sure-grip” rubber handle and ladder hook
  • Easy start-up procedure: Insert fuel cell, insert battery, load pins and begin use
  • Easy to clear a fastener jam
  • 45-pin capacity magazine
  • 8,000 shots per Li-ion battery charge

Minimum Cleaning Required
The G3 gas-actuated tool 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 the maximum level of productivity, periodic cleaning is recommended.

  • Only requires cleaning every 20,000 shots
  • Easy access to the air filter and piston chamber
