    Mount flanges to air handlers and HVAC equipment to start a run of duct. They also create a secure joint between sections of duct—attach a flange to each piece. Also known as angle rings.
    With Mounting Holes—Ready to install, these flanges secure with screws.
    Without Mounting Holes—Drill your own holes or weld into place.
    Corrosion-Resistant 304 Stainless Steel—The most corrosion-resistant metal duct we sell. It won’t rust or degrade in systems that exhaust chemical fumes or vent heat from industrial ovens and dryers.
