This product consists of four replacement heat plate burner cover parts made of stainless steel, designed for BBQ gas grills with four burners. The heat tents are black in colour and are essential components for maintaining even heat distribution during cooking on the grill. These durable covers help to keep your grill operating efficiently and effectively, making your outdoor cooking experience more enjoyable and hassle-free. They measure approx 38cm total length, 9.5cm width. I believe they originally came from a Homebase Stardom 4 burner gas bbq, but may fit other makes and models.
