If your chimney has two or more flue tiles, this is the correct cap. I fabricate every multi-flue cap to your exact chimney dimensions from 18×18 up to 60×120, in my shop in Berlin, NJ.\u003c\/p\u003e\n\u003cp\u003eEvery cap is hand-fabricated to your exact dimensions — the same way it's been done in my shop since 1994.\u003c\/p\u003e\n\u003ch3\u003eWhat It Actually Does\u003c\/h3\u003e\n\u003cp\u003eA properly fitted cap does four things a hardware store cover doesn't: it protects the entire chimney crown (not just individual flue tile openings), it blocks animal entry with a heavy spark screen, it reduces wind-driven downdraft, and it contains embers from wood-burning fireplaces. The full-perimeter flange sits on the crown — crown repair runs $500–$3,000, and a cap that covers it correctly prevents all of it.\u003c\/p\u003e\n\u003cp\u003e\u003ca rel=\"noopener\" title=\"What Is a Chimney Crown and Why Does It Crack\" href=\"https:\/\/archaicmetal.net\/blogs\/resources\/what-is-chimney-crown\" target=\"_blank\"\u003eWhat is a chimney crown — and why yours may already be cracking →\u003c\/a\u003e\u003c\/p\u003e\n\u003ch3\u003eBuilt for Multiple Flues\u003c\/h3\u003e\n\u003cp\u003eThe multi-flue cap uses a taller screen panel than a standard single-flue cap — 10\" is the default, with options up to 24\" — to clear multiple flue tiles that may sit at different heights above the crown. One cap, one installation, full coverage. The cross-brake lid sits on top and removes without tools for chimney sweeping or flue access.\u003c\/p\u003e\n\u003cp\u003eMeasure the full outside of your chimney at the crown — not individual flue tiles — and enter that single width and length in the calculator above. That's your cap size.\u003c\/p\u003e\n\u003ch3\u003eCross-Brake Removable Lid\u003c\/h3\u003e\n\u003cp\u003eEvery multi-flue cap includes a cross-brake structural lid standard — a single-piece lid with a built-in cross-brace for rigidity across the full span. On a multi-flue cap, the lid can be substantial — some span 4, 5, even 8 feet across — and the cross-brake keeps it flat and rigid under its own weight and under snow load. Locks down in place when installed and removes without tools for chimney sweeping or flue access. Standard on all materials and all sizes.\u003c\/p\u003e\n\u003ch3\u003eMaterial Options\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003e16oz Copper\u003c\/strong\u003e — warm penny tone new, weathering through rich browns and eventually to the classic verdigris seen on historic buildings.
