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.

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.

No additional fittings or collars needed.

No additional fittings or collars needed.

Connect diffusers to duct.

Evenly disperse airflow into a room to maintain a consistent temperature throughout the space.

Guide air toward your workspace or deflect unwanted drafts with these diverters and covers.

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

Mount these louvers through an outside wall and control airflow from the inside by adjusting the register.

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

Mount these louvers into openings that are too small for most louvers. They are sized for use in block and brick walls.

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

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

A spring-loaded fusible link locks the blades closed if the temperature reaches 167° F. Louvers meet UL 10C fire requirements.
