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

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

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

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.

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

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

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