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.

Straight Collars
Male with Gasket
Collars create branches from a rectangular duct. Cut a hole in the duct and use a collar to attach standard duct. Collar with polyethylene gasket is self-sealing because the gasket has an adhesive back. The flange has 1/8" dia. mounting holes.
