Adapters join quick-disconnect duct to other duct systems. Duct-to-duct adapters connect to standard and spiral duct. Duct-to-duct with flange adapters provide a secure connection between duct. Duct flanges are also available. Duct-to-hose adapters are slightly undersized. Slide hose over the adapter and hold it in place with a hose clamp (not included).
