The SMI Stainless Steel Spigot Flue Adapters are made from 304 grade stainless steel in a 2B matt finish and in 0.55 sheet gauge thickness. They are designed for a dual flue system with the inner smaller flue section passing through the inside clear of the raised vertical spigot with the outer larger flue section locating on the raised vertical spigot.
