Do you carry any smooth wall heavy liners in 316 ss? inside chimney with existing tile liner (8x8 tile with id of 7x7)) with pieces flaking off. I am not sure an insulated 6" liner will fit. Robert Graves asked on December 20, 2021

Yes, we do carry the National Chimney M-Flex Pre-Insulated Stainless Steel Basic Liner Kit. The pre-insulated 6" liner has an outside diameter of 7", so it could be a tight fit.
