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

Crush-Resistant Spiral Duct and Fittings

Fittings have gaskets which create a tight seal—you don't need to seal joints with coating or tape.

Chemical-Resistant Duct and Fittings

Made of PVC plastic to withstand acids, alkalies, salts, and other corrosive vapors and fumes.
