Standard Duct and Fittings
No need for clamps or connectors—duct and fittings press-fit together. Male ends are crimped or tapered, making them slightly smaller than a female end for simple assembly.
Galvanized steel has good corrosion resistance. Aluminum is more lightweight than steel and stainless steel and has good corrosion resistance. 304 stainless steel is more corrosion resistant than steel and aluminum.

Fire-Rated Airflow Dampers
In the event of a fire, these dampers automatically stop airflow through duct. They have a fusible link that melts at 165° F, releasing a spring and causing the blades to close. Dampers meet UL 555 fire safety standards to help prevent the spread of fire for 1 ½ hours. They are undersized to fit inside duct.
