UNILOK FR1 Acoustic Ducting is a flexible duct manufactured "tough" & "whisper quiet" for consumer & installer peace of mind. Unlike other types of flexible duct, UNILOK FR1 has an outer steel rib that ensures the products integrity, and correct diameter, even in the tightest bends.
Due to its steel rib, it is not prone to glue failure or fatigue (sagging or ovalization) from vibration with age like plastic ribbed or non ribbed glued duct.
