Outside mount chimney caps fit
over the entire chimney, like the lid on a shoebox. The Vertical Skirt on Outside Mount chimney caps attach to the sides of the chimney with screws or chimney capm adhesive. Many of our
customers prefer the nicely finished look these chimney caps provide.
Because chimneys are hand made, their dimensions
often vary a bit. Most outside mount chimney caps are custom made because of variations in chimney dimensions. Such custom made chimney caps can be
constructed of stainless steel or copper with the design features you want, such as a hip and ridge top and a vertical skirt of the height you specify. The
stainless steel can be powdercoat finished with an exterior grade paint in your choice of color.
Only our Band-Around Chimney Caps are available in stock sizes as well as custom sizes. These Band-Around Chimney Caps tighten at each corner of the chimney for a secure fit. The stock sizes of the Band-Around Chimney Caps, available for immediate shipment, are made of aluminum. Custom Band-Around Chimney Caps can be constructed with aluminum or stainless steel.
Measure how far down the side of the chimney you want the chimney cap to cover. This is referred to as the Vertical Skirt Height (see blue arrow on diagram above) and a 3 inch
vertical skirt height is standard.
Measure for your chimney cap's Horizontal Skirt Width (see green arrow on diagram
above.) The standard for horizontal skirt width is two inches and will work fine as long as none of your flues is within two inches of the edge of the chimney.
Measure for your chimney cap's Lid Overhang (see purple arrow on diagram above.) The
lid overhang serves like the eaves on a house. The standard overhang is 3 inches, but you may
wish to make it larger (up to 7 inches) to give your chimney cap better visual proportions if you have a wide horizontal skirt width and a screen height taller than 12 inches.
Select a standard, flat lid (such as the one on the diagram above) or a lid with a pitch. See Lid Styles A through Jbelow. The first number above each diagram, such as 3/12, is the roof pitch
and the second number, such as 14o, is the degree of the roof's angle.
Select stainless steel or copper for your chimney cap's material. Stainless steel can be powdercoat painted with a color of your choice.
Select standard 3/4" mesh screening or a tighter, 5/8" mesh screening if you live in California or in an area at risk for wildfires.
Decide if you want a baked on, exterior grade powder
coat finish paint. Standard Black, Old Penny Copper Brown or other colors. Click on the mini
