Forever® Copper Multi Flue Chimney Caps

100% Solid Copper. NOT Copper plated Stainless Steel. Made in the USA. Lifetime Warranty. Protect the entire chimney's crown and flue from deterioration. Removable hood for easy cleaning. The knock-down design saves on shipping costs. Standard 10" screen height. Animal-proof 3/4" oval hole mesh. Wide 1-1/2" flange for easy installation. For the correct size, measure the overall chimney's crown, both length and wide. Then subtract 3" from both the length and wide, and match that size to the closest size from the caps list below. Please Note that your chimney's flue MUST BE 5" or less to maintain proper drafting. PLEASE NOTE: All Copper Caps are made to order; therefore, they are not returnable or refundable. So, please double-check your measurements.
