Product title: DEWALT D51845 Round Head 2-Inch to 3-1/2-Inch Framing Nailer
Product description: The DeWalt D51845 Round Head 2-to-3-1/2-inch Framing Nailer comes with a 7.6-pound magnesium housing and aluminum magazine, making this nailer one of the lightest nailers in the industry. A unique engine design generates power to bury nails in both standard framing lumber and engineered lumber with minimal recoil, and a tool-free adjustable depth allows for quick and easy depth of drive setting. Also included is a tool-free quick release jam clearing feature that eliminates downtime by removing bent nails caught in the nose piece. Other features include an integrated rafter hook that allows for increased versatility on the job site, and a dry fire lockout that extends bumper life by preventing the tool from actuating when the magazine is empty. Also included is an impact-resistant exhaust deflector that protects damage to the cap and a trigger lock-off that allows the trigger to be disabled when not in use. This nailer comes with a pair of DeWalt safety glasses and a replacement bump trigger., DEWALT D51845 Round Head 2-Inch to 3-1/2-Inch Framing Nailer
