Chimney Flue Cover — Top Mount Single Flue Cap | Fits 8×8 to 13×13

Most chimney flue covers are designed to clamp onto the clay flue tile — friction is what holds them in place. Mine mount to the chimney crown with a full-perimeter flange that can be set in elastomeric adhesive. The lid removes when you need access. The look is handmade, not off-a-shelf. Same footprint as the standard. Better in every other way.

Fits Standard Flue Sizes

This flue cover is 14×14 at the screen area (screen height is custom — message me) and 17×17 at the 1½" mounting flange. Fits outside flue tile dimensions including 8×8, 9×9, 8×13, and 13×13. This is a top-mount cap — it sits on the chimney crown, not clamped to the tile. Need a 13×17, 17×17, 20×20, or 24×24? These can be made in any size. Contact me for a custom quote.

Designed for masonry chimney crowns. Can also be top-mounted on a chase cover using an EPDM rubber gasket — message me if that's your application.

Shipping

Free shipping for standard 14×14 size, USPS Ground with signature. Larger custom caps typically ship LTL freight.

Because every cap ships in a custom-built, heat-treated wood crate — not cardboard — your order arrives in 'New Penny' condition. Fully insured, shipped via heavy-duty freight. If your property can't accommodate a full-sized 18-wheeler, let me know and I can arrange delivery in a smaller truck or pickup at the freight terminal (less expensive option).
