Love cooking breakfast, smash burgers, or stir-fry on your grill? This replacement griddle plate lets you turn your Weber Genesis 300 series gas grill into a flat-top cooking station. It's a perfect fit, dropping right into the same space as your left or right cooking grate (part number 7566). It's made of durable cast iron with a matte enamel finish, so it holds heat evenly for a great sear. The size is 19.5 inches wide by 12.5 inches deep and about 1.5 inches high. It fits a ton of specific Weber Genesis models: E-310, S-310, EP-310, CEP-310, E-320, S-320, EP-320, CEP-320, E-330, S-330, EP-330, and CEP-330 grills. It also matches a long list of Weber part numbers (check the full list in the description). Remember to season it with oil before first use and after cleaning to keep it non-stick and rust-free. An awesome upgrade for versatile outdoor cooking without buying a whole new appliance.
