Allegro Industries 9500-500 Lay Flat Ducting 500', fits 8" and 12" Blowers

Lightweight air ventilation tubing (similar to a plastic bag) manufactured from durable clear polyethylene, has been engineered for maximum elasticity, flexibility, toughness, and resistance to splitting and tearing. Most commonly used for transferring large volumes of forced air to confined areas, such as water restoration projects, building renovations or other temporary applications. This hose is NOT measured by its internal diameter but rather its diameter when laying flat.
