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.

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

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

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

Control the flow of air and material through duct systems.

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.
