The Ryobi PBL345KN packages the ONE+ HP brushless 21-degree AirStrike framing nailer with a 4.0 Ah HIGH PERFORMANCE battery and charger. The on-board AirStrike reservoir (125 PSI) eliminates the need for a gas compressor, making this a truly cordless framing solution for decking, structural sheathing, wall framing, and rough carpentry. The 4.0 Ah battery is the recommended minimum for sustained framing work and delivers approximately 750 nails per charge. The 21-degree plastic-collated full round head magazine holds 33 nails and accepts 2–3-1/2 in. nails in 0.113–0.131 in. diameter. Combined weight with battery is 10.9 lbs. Dry-fire lockout, tool-free depth adjustment, rafter hook, and belt hook are included.
What is included in the PBL345KN kit?
The PBL345KN includes the PBL345B 21-degree AirStrike framing nailer, one 18V 4.0 Ah HIGH PERFORMANCE battery, an 18V charger, a rafter hook, belt hook, hex key, and a non-marring pad.
How many nails can I drive per charge?
With the included 4.0 Ah HP battery, the PBL345KN drives approximately 750 nails per charge under typical framing conditions. This is Ryobi's recommended minimum battery for sustained framing work.
Does this nailer need a compressor?
No. The AirStrike on-board air system maintains an internal reservoir at 125 PSI, good for roughly 50,000 shots before needing a refill via a standard ball-chuck fitting. The battery powers the tool electronics, not the air.
Why is the magazine only 33 nails?
The 21-degree strip configuration is more compact than the 30-degree format. If magazine capacity is a priority on high-volume framing jobs, consider the PBL350B or PBL350K with a 60-nail 30-degree magazine.
What 21-degree nails should I buy for the PBL345KN?
Use 21-degree plastic-collated full round head framing nails in 0.113 in. to 0.131 in. diameter and 2 in. to 3-1/2 in. length. Standard brands such as Grip-Rite, Paslode, and Bostitch all offer compatible 21-degree plastic strip collated nails.
