WT Knowles has published a data page for its Lintel products which complement its extensive range of chimney pots, terminals, inserts and flue liners
The throat lintels are sized by the required flue diameter and are suitable for 200mm, 225mm and 300mm diameter flue liners.
Gather units and spacer lintels are also available which may be used in conjunction with the throat lintels depending on the fireplace opening.
