HOW TO SELECT YOUR SIZE
This listing covers Kynar aluminum and Galvalume multi-flue caps. Also available in 16oz copper and stainless steel — view the Copper & Stainless Steel listing.
Width is always the shortest dimension of your chimney. Measure the outside width and outside length of your chimney top, then add a minimum of 1/4" to each measurement before selecting your size band. Example: 28" wide × 72" long — select Width 25–36" and Length 61–72".
I've been working copper and specialty metals since 1994, and the multi-flue flat-top cap is one of the most satisfying pieces I build. Clean lines, full-perimeter screening, and a single cap that covers every flue on the chimney — fabricated entirely by hand in my Berlin, NJ workshop.
Kynar aluminum is my go-to material for color-matched and low-maintenance installs. It holds paint finishes better than any other material I work with, it won't rust, and it's significantly lighter than copper or stainless steel — an advantage on larger multi-flue configurations. Standard finish is mill aluminum unless a color is specified.
Galvalume is the most cost-effective option on this listing and performs well in exposed conditions. Same fabrication standard, same screen spec, same hand-built construction — just a more budget-conscious material choice for contractors and property managers working at scale.
Screen panels on both materials are 18-gauge expanded stainless steel mesh. Corners are riveted with copper rivets and brass mandrels. Mount type — top mount or side mount — is included at no additional charge; specify at checkout or message me directly.
For sizes outside the listed bands or non-standard configurations, send me your measurements and I'll build it to fit.
