    The Duro-Shield 17 in. x 21 in. Aluminum Band-Around Brick Single Flue Chimney Cover is proof that you don't have to sacrifice any quality by choosing a remarkably well-priced item. Aluminum chimney caps are sturdy, lightweight, and more affordable that caps constructed out of other metals such as copper or stainless steel.

    This chimney caps hood is constructed of solid 18 gauge diamond-embossed aluminum. There is a 16 gauge expanded aluminum mesh to help prevent birds and other critters from getting inside the chimney and causing costly damage. The extruded aluminum braces provide plenty of support, and the stainless steel nuts and bolts help ensure a firm, secure chimney mount.

    Chimney covers are not always made alike. You want quality and performance above all. When you combine maximum function with the best price available, though, there is no better choice than the Duro-Shield 17 in. x 21 in. Aluminum Band-Around Brick Single Flue Chimney Cover.

    Customer Questions & Answers
    By Jake from Rome, NY on August 23, 2015
    What are the measurements of the top (roof) of this Duro-Shield 17 x 21 aluminum band-around brick single flue chimney cover?
    By Will M. on August 24, 2015

    The lid size is 22" x 23".

    By Alixine from Seattle, WA on October 22, 2012
    I was wondering which chimney cap you would recommend for this chimney: it has the flue at the top. The measurements around the narrower part are roughly 16" x 19", and around the wider brick part 20" x 21". I had my eye on the Duro-Shield 17" x 21". Would this be a good fit?
    By Collin C. - NFI Master Hearth Professional on October 23, 2012

    While this cap would fit the 21 inch side of your chimney, it could not adjust large enough to fit the 20 inch side. Likewise, we have a 21 inch x 21 inch version of the same. However, it will not adjust down to the 20 inch side of the chimney, either.

    Due to this odd middle ground, it may be better to go with a cap that will fit around the clay flue tile in which your damper is currently mounted.

    By Ken from Huntsville, OH on December 29, 2015
    My brick chimney is 16 x 21 1/2 x 16 1/2 x 21 1/2 so it is not a perfect rectangle and it has no liner with about a 1" rolled mortar crown. Would this Duro-Shield 17 x 21" aluminum band-around brick single flue chimney cover work for me?
    By Will M. on December 29, 2015

    If it is not lined, you are not going to pass any accepted national standard for a functional chimney. If you are looking for something to simply prevent rain intrusion, a cap like this would be a good solution. However, the cap in question will not work as your 16" measurement is below the minimum width required for this cap. The HomeSaver Pro 17 in. x 21 in. Base California Mesh Black Galvanized Steel Single-Flue Chimney Cap would appear to be a better option.

    By Larry Smith from Kenner Louisiana (New Orleans Suburb) on September 3, 2012
    Would you be able to custom make this cover for my chimney? We just came through Hurricane Isaac and my cover got blown off the roof. The dimensions of my chimney are larger than the cover you guys offer, something like 27 by 23. I would measure to be exact if you can make one for me.

    By Collin C. - NFI Master Hearth Professional on September 4, 2012

    We can indeed custom fabricate a chimney cap for your needs. Please provide the outer dimensions of your chimney flue, as well as the outer dimensions of the masonry.

    Do you know how this cap would hold up on a fuel oil furnace chimney?
    By eFireplaceStore on June 25, 2014

    This cap should do well for a fuel oil chimney. Aluminum, along with 316 stainless steel, are the two materials that hold up best. Stainless steel will be the most durable over the long run, but aluminum will offer years of service before heavy corrosion sets in.

    By John from Tiverton, RI on October 17, 2016
    Do you have any caps that might fit the enclosed chimney? lengths are 19 and 18 9/16 and widths are 17 5/16 and 17 5/8.
    By Will M. on October 18, 2016

    If the dimensions are 19" L x 17 5/16" for one and 18 9/16" x 17 5/8" for the other, the cap in question would work for each.

    By e from lewiston id on September 9, 2012
    How tall is this chimney cover?
    By Collin C. - NFI Master Hearth Professional on September 10, 2012

    Per the manufacturer, the screen height (not including the mounting band) is approximately 6 inches, with another 1.5 inches added from the lid.

    By Jim from Maine on November 23, 2012
    I have an 8 x 12 single flue brick chimney. It burns primarily wood. Is aluminum okay for cap material?
    By Collin C. - NFI Master Hearth Professional on November 23, 2012

    Aluminum caps are indeed acceptable for use as a low cost alternative for wood burning applications. However, they usually do not have as long of a service life when compared to copper or steel.

    Chimney cap is over the top (of the house) in quality!

    This is the only place I could find a chimney cap big enough (23.5"x23.5") to fit around our chimney. I ordered it easily online, it was delivered very quickly and was easy to assemble. It is now on our chimney and keeping the rain and birds out just in time for cold weather to begin. Thank you very much!

    Would have given it five stars, but I don't like the way the wire mesh goes together. Could have been made in one piece and folded or rolled.
    Nice looking, made of aluminum, adjustable.
    I don't like the four piece mesh. Could have been designed much better.

    great product

    pieces and parts were well made..stainless bolts and nuts...plenty of room for adjustment and went together for me and on the chimney in 45 minutes.I needed this to keep the rain out but the screen will keep out the critters...

    Very well manufactured product. Easy to assemble and install. Looks great topping off the chimney, better than the small Inside diameter ones.

    Okay, But...

    Surprised it came unassembled. Easy, though, to assemble on my back porch. Instructions were poor suggesting only the least of interest in that part of the process. The product fit nicely and tightened easily as I balanced on the roof; except for the side farthest from me. The screws, you see, are a single, slotted standard head screw, not the easiest to work with when not in direct sight. Add to that a tottering perch on the top of a windblown roof and the possibility the cover would blow off before the last two screws were tightened and I found myself cursing your design team. Had the band either been secured by either screws with a Philips head or by wing nuts the process would have been much easier. Your company might think of the installer when choosing fasteners, not just acquiring the cheapest product.
