The Lambro® Semi-Rigid 8-Ft. T-LOCK UL® 181 Class 0 HVAC Air Duct 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.

  • UL® 181 Class 0 certified and marked; meets NFPA 90a and 90b
  • 8-ft. length compressed to 26 in.
  • Maximum operating temperature of 600°F
  • All-aluminum design; made from 35-gauge aluminum
  • T-LOCK Triple lock airtight seams
  • Flame-resistant and non-combustible
  • Flexible air ducts shall not be limited in length
  • Installation foil tape or clamps not included
