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.

At about half the height, this oval duct fits in tighter spaces than round and rectangular duct.

Save energy and increase comfort by heating and cooling only the areas that need it.

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

In the event of a fire, these dampers automatically stop airflow through duct.
