Built to last, this medium crown stapler has a piston ring design that prevents cylinder bore scuffing and lasts longer than conventional "O" rings. It will drive 16-gauge, 7/16-inch crown "N" wire staples from one to two inches long. The open top-load magazine makes for easy reloads and will hold up to 150 staples for less down time. An adjustable depth-of-drive mechanism allows countersinking fasteners to match the application. The bump-fire trigger allows for faster operation. Also, though it comes with a 1/4-inch quick coupler, the air inlet is 3/8-inch NPT. This allows the option of using a 3/8-inch quick coupler for better airflow in high-production applications. A quick-release nosepiece is also standard for faster clearing of jammed fasteners. Includes stapler, carrying case, 1/4-inch male quick coupler plug with dust cap, oil, allen wrenches, and operator's manual.
