    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.
    90° Elbow Register Boots
    Image of Product. Front orientation. Duct and Fittings. Standard Duct and Fittings, 90° Elbow Register Boots.
    Create an angled airflow path from duct to vents or registers. These boots are commonly used with heating and cooling systems to deliver air through walls and ceilings.
    Galvanized Steel—Corrosion resistant and affordable, galvanized steel is the most commonly used ductwork material.
