GrillGrates with the GrateTool are the ultimate upgrade for any gas grill. Whether you go on top of your existing set or entirely replace your stock grates, 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. Made in the USA. The GrateTool is made in China.
