Q:Can you please explain how the notched corners should be utilized in connecting sections without cleats? (i.e. you indicated "notched corners are for easily connections, or use cleats"). So how are they sections connected without cleats?

Q:Product does not match pictures. Why are deep notches cut on flat flange? Using s & drive cleats leaves gap when joining another section. Please help.

          Notches on corners are incorrect
          Product has notches cut on corners that will leave gaps when installing with s-clear & drive cleats. Called Home Depot Customer Service, and was told to return it or "you know, sometimes you just have to do it yourself. I do it myself all the time" (direct quote from Customer Service). Read review further down. You will have to cut every flange in order to have ducts properly join to another.

            Junk
            These things are just plain awful. First they're super-thin... the foil you wrapped your leftover turkey with last Thanksgiving is probably stronger. Second: whoever or whatever did the bending on these seemingly would not know a 90-degree angle if it fell on their head. And as another reviewer mentioned, the sections don't lock together properly. On the first two I tried, out of 8 feet of "seam", I'd say 6" locked, the rest won't. Absolutely not worth the cost.

                Very convenient, parcel was packed very well.
                I was worried this would arrive all bent up since it is big and flimsy before being assembled. But it was actually in pristine shape. Better than similar ductwork found in-store.

                  Good product but requires a little skill to use
                  I have to admit I've never worked with metal duct before. Product is well-made and easy enough to fit together into a rectangular duct. I needed an 8' long duct so I put 4 pieces together, hardest part was lining up the two ducts end-to-end and fastening with sheet metal screws. Result ended up a bit cockeyed but my lack of skill contributed to that. Would buy again.

                  Flimsy. Didn't lock together, had to use zip screws to hold it together. Top and bottom flanges were too long to use the channel hardware you are supposed to. I needed to cut every. single. flange. Really, I didn't even want to put a second more into this product to make a review. But home depot keeps sending me emails, over and over, hoping I give the chineseium a good review? It's thinner, and less ductile than anything you'll find at an actual plumbing supply place. And therein is the problem. You want to do home repairs DIY, mostly to save money, and for years you've demanded lower prices. Well, now you get 1 choice of the worst possible product, made by people that obviously hate you to make a product this bad. It also makes tradesmen, with a tax number, who can buy at actual plumbing supply stores, look like magicians. Because the product is so much better, and easier to use.
