HVAC Air Duct
The Lambro semi-rigid 5-inch x 8-foot T-LOCK UL 181 Class 0 HVAC air duct with one crimped end is ideal for use in supply, return, or exhaust systems.
This air duct offers flexibility with its corrugated design, which prevents collapse and allows for easy bending when needed. Constructed from 100% aluminum, it is corrosion-resistant, non-combustible, and flame-retardant, capable of enduring temperatures up to 600°F.
The T-LOCK design consists of a lightweight, flexible air duct made from a dead soft aluminum strip that is spirally wound and mechanically fastened, forming a leakproof and airtight triple lock seam.
When installing, there are no restrictions on the length of the air duct. Each section of this certified UL 181 Class 0 air duct bears the UL certification mark.
It is important to check local building codes before installation.
