    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.

    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.
    Lightweight Aluminum—One-third the weight of steel, aluminum ductwork is easier to handle during installation. Like galvanized steel, it resists rust in wet environments but won’t last as long.

    Blast Gates for Quick-Disconnect Duct

    Image of Product. Front orientation. Duct Blast Gates. Blast Gates for Quick-Disconnect Duct.
    Slide these gates open and closed to control airflow to sections of quick-disconnect duct. Unlike dampers, which regulate flow, blast gates turn flow on or off. They’re commonly used in dust collecting systems, either to direct suction or collect material in a specific section of duct. Secure gates to a line using quick-disconnect clamps.
    Aluminum with Galvanized Steel Slide—Our most popular blast gates. The body is aluminum to reduce stress on your duct and the slide is galvanized steel for strength. Both components resist rust in wet environments.
