Product details:

Ideal for oil, coal or heavy wood burner chimneys, the Draft King Round Bolt on Single Flue Stainless Steel Chimney Cap is constructed of 100% 304 stainless steel and built to withstand the toughest of conditions. This cap's durability is rugged enough to tackle any application within 25 miles of a saltwater coast. Its high-quality construction includes a 24-gauge stainless steel hood with scalloped corners and roll-formed edges, an 18-gauge 3/4 in. expanded stainless steel mesh and a 16-gauge stainless steel base integrated for added strength. Like all Draft King chimney caps, the outside mounting design engineers a maximum free air space, allowing uninhibited chimney draft. 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. This bolt on chimney cap fits outside tile dimensions 11-1/2 in. to 12-1/2 in. round.
