The Triple Lock T/L system by Flexmaster is a lightweight, semi-rigid, non-insulated air duct. It's made using a dead soft aluminum strip which is spirally wound and mechanically joined together. This forms an air-tight and leakproof three-ply mechanical seam. It is self-supporting and corrosive resistant. With its ULC-S110 and UL-181 Class 1 rating, it provides excellent strength and flexibility. It is adaptable to any heating, ventilation and air conditioning system, even with high-pressure.
