The Cast Iron/Porcelain Grill Grate Kit includes two dynamic cooking surfaces to boost your grilling skills. The cast iron grate has even heat distribution across the entire grate and gives a perfect sear to seal in flavor. The porcelain grate has a non-stick surface and cleans easily after grilling saucy ribs or juicy chicken. Upgrade your grill by replacing all of the existing grates and get the upper hand on precision grilling. See less
