The tool is frequently cited as a direct upgrade to the CN445R2, with added benefits like the swivel fitting for better hose management.

The Dotool CN45C is a lightweight pneumatic 15° coil roofing nailer designed for residential applications, featuring tool-free adjustments for depth and jam release. It offers an ergonomic design and 360° exhaust adjustment, but suffers from specification inconsistencies and a lack of verified performance data. Best for DIY roofers and small contractors needing a versatile tool for siding and shingles.
