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 Connectors

Change the direction of airflow when joining lengths of duct.

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.

Quick-Disconnect Duct and Fittings

The fastest ductwork to disassemble for dust collection and other frequently cleaned systems. Join sections with quick-release clamps that open and close with a flip of the latch. Since you don’t need screws, welds, or tools, the installation time is half that of other duct types.

90° Elbow Connectors

Change the direction of airflow when joining lengths of duct.

Spiral Duct and Fittings

Reinforced with a continuous seam, this duct keeps its shape, even against suction from dust collection systems. On the inside, duct is smooth for efficient airflow. Because of its attractive look, spiral duct is often used for exposed heating and cooling systems.
