A flue liner insert with individually adjustable sides, which can be used to fasten to, extend and join two rectangular masonry clay flue tiles. Specifically, this flue liner insert fits into the interior of a clay tile and allows adjustable fastening to existing masonry clay tiles in a manner that can withstand common loads and also not interfere with the chimney draft. This flue liner insert can be used to extend masonry chimneys, join clay flue tiles, anchor ceramic chimney pots, partially or fully line existing chimneys, and mount standard or integrated chimney caps.
