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.
