Used to replace approximately 130 feet of residential fence, 5/8" cedar posts nailed to 2" x 4" pressure treated cross ties, 4" x 4" posts. Shot, 1 time out of 4 you won't have time to release the trigger and you'll get a double fire with two nails sticking out of the wood or two stuck in the nailer. Nail the crossbars to the posts and I had to do a lot of that with a hammer. The instructions say to set the pressure adjustable depth from 70 to 110 psi and that works well. Around 65 psi there is occasional jamming or propulsion Pen doesn't come all the way back I can't tell if the manual depth wheel does anything at all After about the first 200 nails I figured out all those subtleties and hammered over two thousand nails 1-3/4 inch by .09- inch ring shank ASIN B00DNSFQQE, without a single dropout or binding. Each of them is constantly flattening a nail head, maybe 1 in 30 sat up and needed a hammer if I was picky. no longer pay.
