The DeWalt 21-Degree 3-1/4" Plastic Collated Round Head Framing Nailer (DWF83PL) is built for high speed framing applications. New engine technology has been designed to reduce recoil, and the nailers optimized center of gravity results in a well-balanced tool. The recoil dampening engine system improves efficiency, while the tool-free depth-of-drive adjustment ensures the precise setting of fasteners. A selectable trigger allows you to quickly and easily switch between bump or sequential actuation mode. The lightweight design is only 8 lbs. for enhanced ergonomics, comfort & control.
