GrillGrates provide protected, high-heat grilling on the XL Big Green Egg. The bottom plate blocks hot rushing air and flames from charring and drying out food, keeping the juices sizzling with the food instead of feeding the flames. GrillGrates are used on top of the existing grate surface. Every set comes with a GrateTool which is part fork, part spatula that fits between the rails to get under your food and lift it without scraping.Designed for the XL Big Green EggSet Includes: (2) 20" Radius Cut GrillGrate Panels and (2) 20" GrillGrate PanelsCovers 90% of the grilling surfaceGrillGrates sit on top of the existing surfaceGrillGrates are reversible interlocking panels, giving you two grilling surfaces; rails up or on the flat sideConstructed from hard anodized aluminum, GrillGrates will never rustIncludes Grate Tool and User GuideGrillGrates are Made in the USAGrateTool Made in China
