Quick-Disconnect Duct and Fittings
Join duct and fittings with quick-release clamps for faster disassembly and cleanout than other duct systems.
Galvanized steel has good corrosion resistance. Aluminum is lightweight and has good corrosion resistance.

Adapters join quick-disconnect duct to other duct systems. Duct-to-duct with flange adapters provide a secure connection between duct. Duct flanges are also available. Duct-to-hose adapters are slightly undersized. Slide hose over the adapter and hold it in place with a hose clamp (not included).
Airflow dampers regulate airflow.

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.
Connectors with welded seams prevent leaks.

Crush-Resistant Spiral Duct and Fittings
A spiral seam makes this duct strong and rigid. Fittings have male ends with a slightly smaller diameter to press-fit into duct.
Galvanized steel has good corrosion resistance.
Add a noise reducer to duct to decrease noise by as much as 50%.

Duct Flanges
Bolt flanges to equipment to start a run of duct. They can also create secure connections between two duct ends by mounting a flange to each end and then joining the flanges.
Steel, galvanized steel, 304 stainless steel, and aluminum flanges are also known as angle rings.
Galvanized steel flanges have good corrosion resistance.304 stainless steel flanges are more corrosion resistant than steel.
