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.

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.
