the look and fit you need.
Made in America and to your specifications.
Lifetime Warranty! Let this be the last chimney cap you ever need to buy!
Outside Mount Copper Chimney Caps are appropriate for chimneys of any size, with any number of flues.
Copper corner braces, as seen in the photo to the right, can be added as an option.
Heavy duty, 20 ounce copper removable flat lids on the outside mount chimney caps allow for easy annual cleaning by your chimney sweep.
Your choice of copper flat lids with a standard 3 inch lid overhang on all sides or any larger overhang you specify.
The base or skirt is constructed of 20 ounce, heavy duty copper, and you can specify both the horizontal skirt width (how far in from the outer edge of the mesh screening will be) and the vertical skirt height
(how far down the chimney the skirt goes.) The standard horizontal skirt width is 2 inches and the standard vertical skirt height is 3 inches.
The copper mesh screening, which should be at least 5 inches taller than your tallest flue with a recommended 8 inch minimum,
is constructed of 20 ounce copper. Specify the screen height
you want for your outside mount chimney cap up to 24 inches tall.
Is the top of the cement part around your flues (the crown) more than an inch above the chimney bricks? If so, you will
need an elevation between the top edge of the vertical skirt and the bottom of the screen mesh.
The image at the left shows a standard, flathorizontal skirt. Unless you specify an elevation, your Custom
Copper Outside Mount Flat Lid Chimney Cap will be made with the standard, flat horizontal skirt with no elevational rise.
To the right, above, is a horizontal skirt with an elevation. The dotted brown line
represents the number of inches your elevation might need to be. It is the height from where the bottom of the mesh screen will be to the top of the first row of chimney bricks.
Your choice of either standard 3/4 inch copper mesh screening or, for a building in
California or other wildfire prone areas, 5/8 inch copper mesh screening on a copper custom outside mount chimney cap.
The custom copper outside mount chimney caps with flat lids are easy to attach with the included
tapcon drill bit and tapcon screws. Or, if you prefer, you can attach them with discontinuous beads of chimney cap adhesive.
A natural, aged verdigris patina comes with time to an Outside Mount Copper Chimney
Cap. If, instead, you would like to keep the shiny, new gloss of the copper chimney cap, simply apply Copper Protective Coating.
It takes only 3 weeks at most for your copper outside mount chimney cap with flat lid to be custom made for you and ship.
Outside mount copper, flat lid chimney caps must be custom made to fit each chimney since there is so much variation in chimney sizes. To measure
outside dimensions for a custom copper outside mount chimney cap, we recommend using a metal measuring tape or metal yardstick.
First, measure the longest side of your chimney. Then, in a clockwise direction, measure each side in sequence.
Provide us with your exact measurements and your copper flat lid outside mount chimney cap will be built with a 3/16 inch tolerance on each side. Please measure
carefully; as an item custom made to your specifications, an outside mount copper chimney cap cannot be returned for a refund.
Our friendly Chimney Cap Specialists are committed to answering any questions and helping you select and
measure for the chimney cap you need. Just call toll free 888-834-7375 ore-mail us for more information or a quote.
