The Porter Cable Clipped-Head Framing Nailer uses 2 in. - 3-1/2 in. x 0.113 in. - 0.131 in. paper-collated clipped-head framing nails. It has a compact design that fits neatly in its own carrying case. It features an internal piston catch for consistent power with a tool-free depth-of-drive adjustment that facilitates accurate nail setting. It has a non-marring nose tip and adjustable exhaust to direct particulates away from the user. The trigger can be set to restrictive- or contact-actuation mode and a nail lockout mechanism eliminates dry fire to help prolong blade life.
