This is the highest quality duct made, with heavy duty wear strips and two-ply construction, ideal for moving large quantities of air into hard to reach places. Spiral Duct may be used on the intake or discharge side of a fan. It folds up to take very little space when not in use. Once deployed, men and equipment can pass by easily in cramped spaces by simply collapsing the duct. It comes attached to an adapter that clips easily onto a fan.
Light is able to pass through the reinforced translucent vinyl.
