This collapsible, accordion style hose attachment is 15' long, with a 10" diameter. It is great for directing air to confined areas, like cupboards, attics, or heating vents. An absolute must for any water restoration professional. A tightening belt allows the hose to attach to the nose of any one of our air moving carpet dryers. The yellow tube is reinforced with black wear strip, to help the duct keep its form, even when the air mover is turned off. The duct will collapse down for easy transport.
