Ideal for oil, coal, heavy wood burner, and pellet stove chimneys, Shelter's stainless steel chimney cap is constructed of 100% 304 stainless steel and built to withstand the toughest of conditions! This chimney cover'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 straight cut edges, an 18-gauge 3/4" expanded stainless steel mesh, and a 16-gauge stainless steel base integrated for added strength. The outside mounting design engineers maximum free air space allowing uninhibited chimney draft and installs easily with slotted hex-head mounting bolts. An optional heavy-duty stainless steel leg kit (SCLK) is available for use when the flue tile does not extend above the chimney crown. Made in the USA and backed by Shelter's Limited Lifetime Warranty.
