About Duct Connections

Standard Duct and Fittings
No need for clamps or connectors—duct and fittings press-fit together. Male ends are crimped or tapered, making them slightly smaller than a female end for simple assembly.
Galvanized steel has good corrosion resistance. Aluminum is more lightweight than steel and stainless steel and has good corrosion resistance. 304 stainless steel is more corrosion resistant than steel and aluminum.

Quick-Disconnect Duct and Fittings
Join duct and fittings with quick-release clamps for faster disassembly and cleanout than other duct systems.
Galvanized steel has good corrosion resistance. 304 stainless steel is the most corrosion resistant.

Duct with access panel saves you from having to cut holes or add screws for a traditional cleanout door. The built-in panel slides back and forth, giving you easy access to the inside of the duct.

Crush-Resistant Spiral Duct and Fittings
A spiral seam makes this duct strong and rigid. Fittings have male ends with a slightly smaller diameter to press-fit into duct.

Sure-Seal Spiral Duct and Fittings
Fittings have gaskets which create a tight seal—you don't need to seal joints with coating or tape. Fittings have male ends with a slightly smaller diameter to press-fit into duct. These duct and fittings are compatible with Crush-Resistant Spiral Duct and Fittings.

Chemical-Resistant Duct and Fittings
Made of PVC plastic to withstand acids, alkalies, salts, and other corrosive vapors and fumes. Use PVC pipe cement (not included) to secure components. Fittings have female ends with a slightly larger diameter to press-fit over duct.

Automatic Airflow Dampers
Save energy and increase comfort by heating and cooling only the areas that need it. Dampers automatically close when signaled by a thermostat or switch (not included).

Furnace Draft Dampers
Also known as barometric dampers, these dampers improve furnace performance by automatically opening and closing to maintain a consistent airflow despite changing environmental conditions.
Single-acting dampers open inward to prevent strong drafts from pulling too much heat into the chimney vent.
Double-acting dampers open both inward and outward to relieve pressure caused by obstructions and downdrafts.
Fire-Rated Airflow Dampers
In the event of a fire, these dampers automatically stop airflow through duct. They have a fusible link that melts at 165° F, releasing a spring and causing the blades to close. Dampers meet UL 555 fire safety standards to help prevent the spread of fire for 1 ½ hours. They are undersized to fit inside duct.

Dampers for Drop-Ceiling Diffusers
For use with drop-ceiling diffusers and ready-to-connect drop-ceiling diffusers, these dampers regulate airflow. Dampers mount to a collar.
Dampers with a butterfly opening/closing style open on a middle hinge. The removable handle adjusts the damper to control airflow and is easier to adjust than dampers with a radial opening/closing style.
Dampers with a radial opening/closing style open in a circle for more precise airflow than dampers with a butterfly opening/closing style.
