The Rock-Vent Class A Chimney Pipe is constructed from quality materials, comprised of many unique features and backed by warranty. It is a UL Listed system that sits in a class of its own! We offer three different stainless steel options for our Rock-Vent Class A - this chimney pipe selection features a 304L Stainless Steel Inner Wall and Galvalume Outer Wall with .016" thickness. This is a great choice to use for standard solid-fuel applications.
