Rated 5.0 out of 5.0 by Works great and great customer service! Good quality and worked great ... Easy ordering on line... pickup was a breeze. December 14, 2015
Rated 3.0 out of 5.0 by Difficult to rotate. Although in the end this product served it's purpose, unlike some others, I had a very difficult time getting the seems to turn! Even after applying a light coat of lubricant to them, they still proved most stubborn. In fact, one of the two I used had to be disassembled (which I do not recommend) and reassembled in the position needed. I have worked with these types of fitting in the past, albeit in smaller sizes (four, six and eight inch), and have never had such a difficult time getting them to move. Perhaps I just got two from a bad batch. Regardless, I would be reluctant to use them again. November 23, 2014
Rated 4.0 out of 5.0 by Good Product, good price However, It was not carried at my local store and I had to drive to another town to pick them up. Also, they only carried the elbows in twelve inch. I had to go to two different much higher priced stores for 12" take-offs and some 12" in duct pipe. Wasted a whole day rounding up the materials I needed for the project. Realy wish HD had carried the whole line of 12" ducting materials. Side note, applying some air tool oil to the joints from the inside made adjusting the angle of the elbow much easier.

Rated 4.0 out of 5.0 by 0 to 90 Degrees Been re-fitting my duct system and have a few off the wall connections that are totally 0-90 degrees. These can be Adjusted to turn down on one section, to the right on the next, and straighten out for the last. They are far more durable then using flexible 12 inch ducts and will out last the house.

Rated 5.0 out of 5.0 by Great price, and available no where else. We looked all over for 12 inch duct and elbows. While no one else had it, Home Depot did, and at a great price! April 30, 2013
