    • Well made flexible and insulated for exhaust fan
Great quality and easy to work with. I ran two 25 foot sections and connected it with a cheap aluminum connector sealed first with aluminum tape then the 4 inch clamps. The clamps are great but you have to take your time working the pipe over the fittings due to the insulation inside the vent pipe. Be patient. This is a quality vent pipe. I ran it and tapped into an existing outside vent due to foamed attic restrictions. Used a Y connector. Sone say exhaust fans sone work well with more than 20 feet of vent pipe. Mine set at 110 CFM is pushing just fine . Sturdy and won’t calapse . Definitely recommend this product. Great value ... show more

    • Good value
The value is here for the cost, length and quality of this product. I would recommend as it does exactly what it's meant to do. And my husband installed it with ease.

    • 4 inch aluminum vinyl covered duct

Review Image by Alex Alex
This is nothing special. It’s 2 layers, an aluminum inner layer with an outer vinyl cover. It’s NOT insulated in any way and the outer vinyl cover is (approximately) 1 1/2” wide wrap that is NOT attached to the aluminum duct with any adhesive, it will unfurl from the aluminum duct if you’re not careful with it. It does do what it was designed to do and the outer vinyl cover is tuff and gives it a nice, finished look. ... show more

    • Works well
I was upgrading my bathroom exhaust fan and this flexible duct worked well in reaching and maneuvering through some hard-to-reach areas.

    • Good quality
Quality is good. Seems like it will hold up awhile. Insulation is a little less than desired but good overall

    • High quality
Nice product. I used it for new roof vent installs (bathroom, in Florida, don’t need insulated pipe….). Heavy duty enough to work with without ripping but flexible enough work with very easy.
