Increases flue height to increase draft.
Can be used to separate the flue heights of upstairs/downstairs fireplaces to reduce the chances of smoke being pulled down the unused flue when only one fireplace is in use.
Sizes available for all common flue tile sizes. Can be used with round, rectangular, and oval flue tiles. Includes mounting flange.
Specify the flue size, the height desired, and the material above.
