LAMBRO INDUSTRIES 301 3" Aluminum Flexible Duct

This was what I needed, and it was shipped in a timely fashion. A little heavier and stiffer than I would have preferred but otherwise works great. I'm using it to vent a Gene Cafe coffee roaster. 3" corrugated duct is hard to find, 4" is much more common. 4" duct kludged on with duct tape would allow some smoke to escape and, with the windows closed, would set off the smoke alarm. 3" clamps directly onto the large chaff collector now supplied standard with the roaster, and contains the smoke much better.Kudos to Amazon for providing sources of hard to find things.

Good

Going to work great for my boat bilge blower !

As described, quick delivery

Used this to insulate a 1" generator exhaust pipe inside a custom made generator enclosure. Worked out well for that purpose. This product is stiffer than the stuff used for typical dryer vent ducting sold at Home Depot. It will not sag over its length.

I wanted a sturdy and flexible 3" pipe for a auto application and I got it, so I am happy. So many of these things are flimsy and fall apart during installation but these will work nicely.

I bought this hose for a Magic Chef 2.6 cu. ft. dryer that you can find here on Amazon. It will fit the adapter elbow that comes with the dryer. You'll need to flare the end of this hose out a little bit before trying to push it onto the elbow, it's a very tight fit. Also, You're going to want to have a zip tie that is at least 8" long to secure and hold it onto the elbow.I used this hose with a Qualtex indoor vent hose kit. That kit comes with an adapter that will fit this hose perfectly. It also eliminates the need for outdoor venting. This kit comes with a hose, but it's a 4" hose. It has three different adapters included though, one of which will fit a 3" hose. They also include 2 zip ties in the package.See kit here: https://www.amazon.com/gp/product/B00N4RUWMM/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1

This is cheap foil ducting, NOT semi-rigid!
