The Ryobi PBL345B is an 18V ONE+ HP brushless 21-degree framing nailer built around the AirStrike on-board air technology — an internal reservoir pressurized to 125 PSI that delivers approximately 50,000 shots before needing a refill via a standard ball-chuck air fitting. No external compressor is required for framing work. The 21-degree plastic-collated full round head magazine accepts 2–3-1/2 in. nails in 0.113–0.131 in. diameter, covering standard framing, sheathing, and structural applications. The 33-nail magazine is smaller than most pneumatic framing nailers and requires more frequent reloading on high-volume jobs. Dry-fire lockout, tool-free depth adjustment, and a belt hook are included. At 9.3 lbs tool-only it is competitive with comparable battery-powered framers.
Does the PBL345B need a compressor?
No. The PBL345B uses Ryobi's AirStrike on-board air system — an internal reservoir pre-pressurized to 125 PSI. It delivers roughly 50,000 shots before you need to refill via a standard ball-chuck fitting. A battery alone powers the tool between refills.
What nails does the PBL345B accept?
The PBL345B accepts 21-degree plastic-collated full round head framing nails, 2 in. to 3-1/2 in. in length, with diameters from 0.113 in. to 0.131 in. These are the standard 21-degree plastic strip nails available at most home centers.
How small is the magazine?
The PBL345B has a 33-nail magazine — noticeably smaller than the 60-nail magazine on the 30-degree PBL350B or most pneumatic framers. For high-volume framing, expect more frequent reloading stops.
What battery should I use with the PBL345B?
Ryobi strongly recommends a 4.0 Ah or larger ONE+ HP battery for framing work. The motor draws significant current under load, and smaller packs will reduce shots per charge and may trigger thermal protection more quickly.
What is the difference between the PBL345B and PBL350B?
Both are 18V ONE+ HP AirStrike framing nailers. The PBL345B uses 21-degree plastic-collated full round head nails with a 33-nail magazine. The PBL350B uses 30-degree paper-collated clipped or full round head nails with a 60-nail magazine — better for high-volume framing jobs where reloading time matters.
