The Primo Ceramic Reflector Plate for Oval Junior Grill provide dry, indirect heat to the area that they are sitting above. Cook chicken, pizza or anything else that requires a lower, indirect heat. When used separately, different zones can be set up for grilling different foods. Ceramic plates heat up evenly, crisping pizza crusts to perfection. Two “D” shaped plates are included, for covering each side of the oval grills.
