Product Details


Engineered with speed of production in mind, the GREX RN45 coil roofing nailer is designed for fast-air-recycling time. For quick continuous nailing, fast-air-recycling is accomplished with a valve design allowing the RN45 to quickly maximize internal air pressure and power after each shot.
