Broan-NuTone 634M Steel Roof Cap, 6" Round Duct, Black

The Broan-NuTone 634M Steel Roof Cap in black provides a durable and discreet termination point for 6-inch round ductwork, effectively channeling exhaust from bathroom fans, range hoods, or dryers to the outdoors. Its heavy-gauge galvanized steel construction resists rust and corrosion, while the powder-coated black finish blends seamlessly with most roofing materials. The built-in damper operates quietly, preventing backdrafts and keeping out pests, debris, and cold air when the system is not in use. A corrosion-resistant bird screen adds an extra layer of protection, ensuring long-lasting performance in any climate.

Installation is straightforward thanks to the integrated mounting flange that secures directly to the roof deck. The low-profile design minimizes visual impact while maintaining optimal airflow for efficient ventilation. Whether you are completing a new build or upgrading an existing system, this roof cap delivers reliable protection against the elements. Its functional simplicity and robust build make it an ideal choice for homeowners and contractors seeking a no-fuss solution that performs consistently year after year.
