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

Fittings have gaskets which create a tight seal—you don't need to seal joints with coating or tape.

Often used in tight spaces, such as in walls and ceilings, rectangular duct allows you to select larger sizes without increasing duct height.

Evenly distribute air from fans and blowers throughout large spaces.

Weld flanges to equipment to start a run of duct.

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

Use in dust collection systems. The slide pushes through the top of the gate to clear debris.

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.

Connect diffusers to duct.
