    With Mounting Holes

    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.
    PVC—Withstand chemicals that would eat away at most metal duct. It’s often used in systems that exhaust corrosive gases, vapors, and fumes.
