Spiral ducts come in 10' standard lengths and custom lengths up to 20'. Fittings are gasketed up to 20" and flange connections 22" - 30". Flange connections can be ordered in smaller sizes if requested.
Our spiral ductwork is popular for contractors because the products are effective for preventing leaks due to the shape of corresponding joints. Spiral duct setups are known for being quiet, as low-pressure drops result in fewer vibrations moving about a system. Connect sections of your HVAC system together using our spiral duct offerings available in 45- and 90-degree configurations.
