used in porta cable fr350

worked fine installing 1/2" plywood in attic space. make sure you wear eye protection as plastic collating does fly in all directions ^M
and is sharp (as you will find out when you inadvertently kneel on a piece). gave it four stars instead of five because of price. a 5,000 pack of similar nails is around $44.00 at home depot.

Perfect

Just went through my first box of 500, without a misfire using a Porter Cable FR350. I am now ordering more for next project. :-) ^M
