The NR90AD(S1) framing nailer drives paper collated nails from 2 to 3-1/2 in length and features HITACHI’s next generation industrial design. The redesigned head guard allows for faster and easier disassembly process, saving valuable time during tool maintenance. Weighing only 7 lb, it is easy to use all day, while still providing the power of a bulkier, heavier nailer. It can be used for floor and framing, truss build-up, window build-up, subflooring, roof decking, wall sheathing and housing construction.
