The NP50A 23 ga PRO pin nailer has been designed with the professional carpenter in mind. It can drive 23 ga pin nails ranging from 1/2 to 2 in L. The high-grade aluminum magazine not only provides exceptional durability but also prevents jams caused by fastener overlap. The 360 deg adjustable rear exhaust has a build-in silencer to reduce noise pollution and direct air exhaust away from the user or jobsite debris. The automatic dry-fire lockout protects your work piece by not allowing the tool to operate if there are six of less pins in the magazine. The 360 deg adjustable belt hook helps keep the tool by your side at all times. The NP50A for when only the good will do.
