Join duct and fittings with quick-release clamps for faster disassembly and cleanout than other duct systems.

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

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.

These dampers regulate airflow.

A vapor barrier provides moisture protection as these diffusers spread hot or cold air around a room.

No additional fittings or collars needed.

Diffusers come with a collar and damper already in place for simple installation.

Direct air coming out of HVAC systems. Adjust the damper to control airflow.

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

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

These gravity-operated louvers remain open only when air flows, preventing backdrafts.

Get an exact fit for your opening by sliding out these louvers to the width you need.

Constructed with a thick frame and blades, these louvers have a long service life.

Always open, these are our most basic wall louvers.

These louvers are gravity operated. The blades open when your roof-mounted exhaust fan goes on and close when it's off, preventing backdrafts.

With a gasketed sealing kit, these louvers shield your enclosure from dirt, moisture, and weather while regulating heat and stopping condensation from forming inside.

Relieve heat buildup and prevent condensation from forming inside enclosures and other small spaces.
