Draft King Single Flue Chimney Cap

Our black galvanized steel Draft King chimney cap is the durable and economic choice for chimneys in most regions. Like all Draft King chimney caps, the outside mounting design engineers a maximum free air space allowing uninhibited chimney draft. Manufactured with a 24-gauge black powder-coated galvanized steel hood with scalloped corners and turn-down edges, an 18-gauge 3/4" black powder-coated expanded galvanized steel mesh, and a 14-gauge black powder-coated galvanized steel base, this cap stands up to the elements. Using slotted hex-head stainless steel mounting bolts, Draft King's unique corner chimney cap mounting attachment provides the most secure fit possible to a masonry flue tile. These Draft King chimney caps are made in the USA and backed by HY-C's 7-Year Limited Warranty.
