The Pin Nailer 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 360degree adjustable rear exhaust has a built-in silencer to reduce noise pollution and direct air exhaust away from user or job site 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-degree adjustable belt hook helps keep the Pin Nailer by your side at all times.
