The Duo-Fast® Cap Nailer System, Model DF175-CN, makes installing synthetic roofing underlayment and organic roofing felt simpler, faster, and safer than acap manual application. The tool’s in-line design provides balance and consistent driving of nails and caps. It features bump-fire operation and a cap-feed shut off button for easy transition to nail-only fastening. The cap nailer uses standard 120-count roofing coil nails and DuoCaps™ collated plastic caps, which provide a consistent tight seal, preventing moisture from penetrating the deck surface. Plus, the DuoCaps™ holding power eliminates slack in the underlayment, translating into more secure footing for roofing contractors. For more information, visit or stop by booth 485.
