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. PVC-coated steel combines the strength of steel with the corrosion resistance of plastic.

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.
