    Standard Duct and Fittings

    Image of System. Front orientation. Exploded view. Duct and Fittings. Standard Duct and Fittings.
    Deliver air for a range of HVAC applications, including exhaust and dust collection. Our basic duct, the round shape creates smoother, more efficient airflow than rectangular and oval duct. The male end is slightly smaller than the female, so sections join without clamps or tools.
    Rain Caps
    Image of Product. Front orientation. Duct and Fittings. Standard Duct and Fittings, Rain Caps.
    Top off vertical duct and exhaust stacks to prevent corrosion and blockages that can disrupt airflow.
    Galvanized Steel—Corrosion resistant and affordable, galvanized steel is the most commonly used ductwork material.
    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.

    End Caps
    Cover unused duct openings to prevent air from leaking, dust from escaping, and debris from entering. End caps are often used to seal duct after changes to your system or equipment. To make modifications or expand your line, remove the cap.

    Rectangular Duct and Fittings

    Image of System. Front orientation. Exploded view. Duct and Fittings. Rectangular Duct and Fittings.
    Maximize the space in close quarters, such as inside walls and ceilings. As rectangular duct sizes increase, they get wider but not taller. This shape is most often used for heating and cooling inside buildings. Components connect with brackets.
    End Caps

    Barometric Draft Dampers

    Image of Product. Front orientation. Barometric Draft Dampers.
    These dampers improve furnace performance by automatically opening and closing to maintain a consistent airflow despite changing environmental conditions.
    Single-Acting Damper—Single-acting dampers open inward to prevent strong drafts from pulling too much heat into the chimney vent.
    Double-Acting Damper—Double-acting dampers open both inward and outward to relieve pressure caused by obstructions and downdrafts.

    Blade Airflow

    Damper

    The simplest, most reliable way to regulate airflow in standard duct. Turn the lever to adjust the blade.
    Blade Airflow Damper—The most economical choice, these dampers slide into the end of duct. Drill a hole for the damper's bolt and remove the handle. Place the damper inside duct, insert the bolt through the hole, and reattach the handle.
    Galvanized Steel—Strong and corrosion resistant, galvanized steel is the most commonly used ductwork material.
