    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.
    Steel—Strong for a long life, these steel flanges can be painted or coated. Unless it’s finished, steel is best for dry environments.
