DESC: Increased durability and reliability. Off position to prevent draining the battery when tool is not in use. Three to five times faster than powder tools: 42-pin magazine reduces load time. Easy to use: Tool automatically resets piston. No recoil, tool absorbs shock resulting in less operator fatigue. No licensing required: Unlike powderactuated tools, no licensing is required. No changing loads: TrakFast uses a fuel cell, not a load. No need to inventory different colored loads. Narrow nose & profile allows tool to reach inside deep leg track (1-5/8" wide x 2" high).
