GrillGrates with the GrateTool will transform the way your Primo XL Oval Kamado Grill cooks. GrillGrates are reversible interlocking panels, giving you two (2) grilling surfaces; rails up or a flat top. GrillGrates tame flare-ups and even out the hot and cool spots common with all gas grills. This gives you even, stable temperatures across the cooking surface. Constructed from hard anodized aluminum, GrillGrates will never rust and are able to withstand heat up to 1,000 degrees Fahrenheit.
