Dimension: Duct Length: 25 feet; Duct Diameter: 4 inch. Review: Great price and great construction. - These are exactly as described. For $15 I got two of these in a box. At my local big box store they were 16 bucks just for one. The metal sheeting is thick and durable. Sometimes when you attach these to the connectors the foil will tear but these didn’t tear at all and went on great. It came with four screw down clamps which was awesome it saved me a trip to the store. They went on easily and cinched down tight without breaking. Awesome value and great performance I’d buy them again when I need them.
