The RIDGID 2-1/2 in. 16-Gauge Straight Finish Nailer has an internal piston catch for consistent driving power and a magazine that allows a wide range of fastener diameters. It offers a comfortable grip and lightweight magnesium housing that help reduce user fatigue and no-mar pads to avoid scuffing or damage to the work surface. The selectable trigger can be set to contact or sequential fire mode and nail jams are easily released without tools. This tool also features a swivel connection to help minimize hose tangles and a rafter hook to keep it conveniently out of the way between uses.
