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.
