No need for clamps or connectors—duct and fittings have a male end that is slightly smaller than its female end for simple assembly.
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.
Fittings have gaskets which create a tight seal—you don't need to seal joints with coating or tape.
Often used in tight spaces, such as in walls and ceilings, rectangular duct allows you to select larger sizes without increasing duct height.
At about half the height, this oval duct fits in tighter spaces than round and rectangular duct.
Evenly distribute air from fans and blowers throughout large spaces.
Bolt flanges to equipment to start a run of duct.
Weld flanges to equipment to start a run of duct.
The panels open and close by turning the knobs.
Regulate airflow by adjusting dampers from fully open to fully closed.
Save energy and increase comfort by heating and cooling only the areas that need it.
In the event of a fire, these dampers automatically stop airflow through duct.
Also known as cleanouts, panels cover cutouts in duct to provide access for inspection and cleaning.
These noise reducers mount directly to spiral duct to decrease noise by as much as 50%.
Add a flexible joint to your system to reduce vibration caused by fans and blowers.
For use with gas-fired equipment, such as boilers and furnaces, these vent pipes and fittings withstand temperatures up to 400° F. Also known as type B gas vents.
Built to withstand temperatures up to 1000° F, these vent pipes and fittings are for use with boilers, furnaces, stoves, and other equipment that is fired by coal, gas, oil, propane, or wood.
Metal interlocked strips create a rigid, durable hose that stays strong under high temperatures.
Formed by metal interlocked strips, this hose has the strength to stand up to sharp, abrasive materials.
Slide these seals over roof flashings for added protection and to create an extra-watertight seal without the need for caulk. They’re also known as storm or rain collars.
