GrillGrates with the GrateTool are the ultimate upgrade for any grill. Whether you go on top of your existing grates or entirely replace them, you’ll notice the difference. GrillGrates are reversible interlocking panels, giving you two grilling surfaces; rails up or on the flat side. 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.
