The MAX USA CORP SuperRoofer CN445R3 is a lightweight pneumatic 15° coil roofing nailer designed for driving wire-collated nails up to 1-3/4" with a full round head driver. It features rapid-fire actuation, tool-free depth adjustment, and an 8x more tar-resistant nose compared to conventional tools, making it ideal for high-volume professional roofing and siding applications. The tool is frequently cited as a direct upgrade to the CN445R2, with added benefits like the swivel fitting for better hose management.

The BHTOP CN45N is a pneumatic 15-degree roofing nailer with a high-capacity magazine and durable aluminum alloy body designed for professional use. It features an extremely low jam rate and heat-treated drive pins, though it lacks verified performance data and operating pressure specifications. Best for professional roofers performing large-scale projects requiring rapid shingle installation.
