Fast, simple, and built to last. The PneuTools 21-Degree 3-1/2" Plastic Collated Framing Nailer (SN2283H-AD) is the adjustable depth-of-drive version of the classic style framing nailer. Just like the standard SN2283H, which so many have come to love, this tool features a single-mode trigger to optimize speed and durability and a hardened, solid metal end cap and an aluminum magazine. These upgrades eliminate unnecessary damage from heavy usage and keep your tool running longer. The SN2283H-AD shoots up to a 3-1/2″ 21° plastic collated strip framing nail.
