This nailer is model PC 350, and handles 3 1/4" thru 2 3/8" clipped head nails. It works great, and includes the rubber boot for the tip for installing siding ,5 boxes of nails, and an adapter coupler. I bought this new and it has been kept in its case always. I have had this tool for a long time but it has only had homeowner type use not commercial use. Most of the boxes of nails are nearly full.
