This porcelain cast iron griddle is two sided. Flat on one side for bacon, eggs, pancakes or whipping up a mess of fried onions and mushrooms. The second side is ribbed, great for fish! 12 1/8 wide by 14 5/8 deep, it is designed to replace the cooking grill on all medium sized Broil King barbecues with the same size cooking grill. (Monarch's 2002 and prior, Regals and Sovereigns) Will fit on almost any other barbecue - just palce it right on the existing cooking grills! (Broil King / OMC Part number 11216)
