Overview
The FR350B is an air powered nailer, weighing 7.3 pounds with a body measuring 21 by 5 by 15 inches. Its 3-1/2 inch nail rating and dimensions point to a framing nailer built for structural work rather than trim or finish jobs.
As a pneumatic tool it needs a compressor and air hose rather than a battery, which keeps it lighter than most cordless framing nailers but ties it to a compressed air setup. Its listed 3-1/2 inch capacity and blend housing material match the size and build of a nailer meant for framing lumber, not light trim.
- Air powered operation
- Rated for 3-1/2 inch nails
- 7.3 pound body
- 21 x 5 x 15 inch dimensions
Who it's for
Framers and builders who already run a compressor on site and want a nailer sized for structural framing nails. Not a fit for finish carpenters who need a compact brad or finish nailer.
Pros and cons
- Air powered so no battery to charge
- Sized for 3-1/2 inch framing nails
- No battery weight added to the tool
- Requires a compressor and air hose on site
- Bulkier than finish or trim nailers
- Blend material construction is not detailed further
Performance notes
Air power delivers consistent driving force as long as the compressor keeps up, without the weight or charge time of a battery pack. At 21 by 5 by 15 inches and 7.3 pounds, it is sized more for two handed framing work than one handed finish nailing.
