Drive concrete nails from a standing position with a single blow from this tool. Outer sleeve tube guides the inner driver bar to drive nails and eliminate wall damage caused by hammer misses. Driver bar features a replaceable magnetic tip which allows loose nails to be ‘picked up’ and held by the magnetic tip without stooping or bending over. Made of heavy duty steel, the Stand-up Concrete Nail Driver has a top handle with a cushioned grip. Overall length (not extended) is 47-1/2" and weighs 11-1/2 lbs. Note: Our No. 870-RMT Replacement Magnetic Tip might have a different thread than other manufacturers. As such, we can only guarantee that it will fit our No. 870 Stand-up Concrete Nail Driver.
