The Topmaster chimney hood belongs to the latest generation of chimney hoods. A Topmaster chimney hood can be placed under a wrought iron decorative hood. This prevents smoke development under the decorative hood and prevents bird nests. In this way, a wrought iron decorative hood can retain its charm and does not have to be wrapped all around in bird or chicken wire. Sweeping the chimney remains a piece of cake because this cap also has a sweeping hatch. The chimney hood does not have to be removed for sweeping. The Topmaster chimney hood is widely applicable, protective, practical and safe.
