The High Pressure Banjo Burner is one of our most powerful cast iron burners. This cast iron burner is the same burner found in the KAB4 outdoor propane burner. In order to obtain a nice, crisp flame, you will need an adjustable regulator. For best results, we suggest purchasing a regulator (7850, 0-30 PSI) and a propane hose (7906, 7908, 7910). The face of this cast iron burner measures 10 inches in diameter.
