Our 135mm bonnet insert is an ideal product for capping older chimneys or flues that are no longer in use while still allowing airflow. The clay bonnet has a traditional red colour that smoothly blends itself in with roof tiles to leave a professional finish. Not to be used with active flues or fires.
- For use on REDUNDANT flues/chimneys only
- Prevents birds from nesting in the flue
- Fits both new and existing chimney pots
