No need for clamps or connectors—duct and fittings have a male end that is slightly smaller than its female end for simple assembly.

A spiral seam gives this duct greater strength and rigidity than standard duct.

Made of PVC plastic to withstand acids, alkalies, salts, and other corrosive vapors and fumes.

Evenly distribute air from fans and blowers throughout large spaces.

Weld flanges to equipment to start a run of duct.

Often added to existing systems, these gates install without disassembling duct. Also known as half gates.

More convenient than other blast gates, these automatic gates open and close in sync with dust collectors, fume exhausters, and other machines.

Regulate airflow by adjusting dampers from fully open to fully closed.

Also known as barometric dampers, these dampers improve furnace performance by automatically opening and closing to maintain consistent airflow despite changing environmental conditions.

Slide these connectors into the ends of duct hose and secure with a clamp.

These short lengths of hose have a collar on each end to prevent the clamp from slipping off.
