We’ve merged two amazing features into one kit. The Cast Iron & Porcelain Grill Grate Kit includes two dynamic cooking surfaces to enhance your grilling game. The cast iron grate distributes heat evenly across the entire surface and gives a perfect sear to seal in flavor. The porcelain grate is non-stick and cleans up easily after grilling juicy burgers or saucy ribs. Replace all of the existing grates to give your grill a fresh upgrade.
