The NP50A 23-gauge pro pin nailer has been designed with the professional carpenter in mind. It can drive 23-gauge pin Nails ranging from 1/2 In. to 2 In. in length. The high-grade aluminum magazine not only provides exceptional durability but also prevents jams caused by fastener overlap. The 360° adjustable rear exhaust has a built-in silencer to reduce noise pollution and direct air exhaust away from user or jobsite debris. The automatic dry-fire lock-out protects your workpiece by not allowing the tool to operate if there are 6 or less pins in the magazine. The 360° adjustable belt hook helps keep the NP50A by your side at all times.
