The PneuTools MC150 is a single-blow joist hanger nailer that is designed to reduce fatigue, eliminate fragile parts, and reduce misfired nails. An open-nose design allows you to clearly see the nail tip and place it exactly where you want it to go, which reduces nose breakage and makes the tool safer to use. It also features a negative-style safety mechanism, which means that it takes less physical effort to fire the tool. The MC150 is ideal for users that prefer single-shot joist hanger tools and a negative-style safety mechanism.
