will it stop downdrafts ?

Asked by: jim
Thank you for contacting MasterFlow ... Our chimney caps will prevent most but not all down drafts. Depending on the angle and velocity of the driven wind, down drafts are still possible. Our caps do not use any type of back draft damper system. Please call our Technical Services Group M-F, 8A-5P EDT, to discuss this issue, 800-211-9612.

9 in. x 18 in. Galvanized Steel Adjustable Chimney Cap in Black is rated 4.3 out of 5 by 18.

My chimney top is 9-3/4" wide by 17-3/4" long, and this cap works perfectly for it. I did have to whittle away a portion of one side of my chimney with my hammer to make one of the clamps fit over it, but wasn't a major issue for me. The cap is lightweight and all metal, but the clamps are very sturdy and strong. We've recently had very high winds, and the cap has stayed in place even with just two sides clamped down (two sides because one clamp went down my chimney, and the other has to be accessed to tighten it down with a bigger ladder, which I don't have yet). A word of warning: make sure to be careful when you put the cap in place because the clamps can come loose. As I mentioned, one of them fell off and went down my chimney stack. However, I called the company, and their customer service was very accessible and easy to work with to take advantage of my warranty. Overall, I've had a great experience.

Rated 4 out of 5 by from Great Price and It Fit the oval Flue! Looked all over for stores and online sources and chimney specialty sources to get a chimney cap for a 45 year old fireplace with an oval flue. This was the only one I could find that sounded like it would fit - sounded like it would be very adjustable. The price was also about the lowest of any cap I saw advertised. The price range on caps was incredible - from around this one's price to hundreds of dollars for the same approximate chimney flue size. I am a senior citizen and did not attempt to climb on the roof to install it. But the worker who did it for me had no problem, said it fit. From down below it looks nice. Has weathered one rainy/windy event and stayed put so thus far am very relieved to have found a satisfactory cap. FYI our flue was one surrounded by a mortar collar and measured about 9-10" by 18-19" ( I of course did not measure it but the person who did apparently was accurate enough).
