Napoleon Cast Iron Cooking Grate for 18" Kettle Grills or Fire Pits (S83019) is built for cooks who want stronger searing performance and easier fire management from a compact kettle setup. Standard grates can make it harder to hold steady heat or add charcoal and wood during a cook, but this porcelainized cast iron grate helps solve that with better heat retention and dual hinged access panels.
Designed for 18-inch kettle grills and compatible fire pit applications, this replacement grate gives you the control needed for both hot-and-fast grilling and lower, steadier cooks. The hinged sections let you refuel without removing the whole grate, making it easier to stay focused on the food instead of fighting your setup.

Will this fit my 18" kettle grill?
This grate is designed for 18-inch kettle-style grills. Because sizing can vary slightly between brands, it is best to measure your current grate before purchasing. It's compatible with Napoleon 18" Charcoal Kettle NK18K-LEG-3.
What makes cast iron better than standard steel grates?
Cast iron retains heat more effectively, which helps create stronger sear marks and more consistent cooking temperatures across the cooking surface.
Why are the hinged sides important?
The hinged panels let you add charcoal or wood chunks without removing the entire grate, helping you maintain heat and keep your cook moving smoothly.
Do I need to season this grate?
Because it is porcelain-coated, it does not require traditional seasoning. A light coat of oil before and after use can help maintain long-term performance.
Can this be used for both grilling and smoking?
Yes. The hinged design makes it easier to manage fuel and add wood during the cook, so it works well for both direct grilling and lower, slower cooks with smoke.

With over 35 years of smoking experience, we started DDR BBQ Supply with a simple goal: to help others cook better barbecue. We've spent decades learning what works and what doesn't, and we apply that knowledge to every product we carry. From high-performance grills and smokers to carefully selected rubs, sauces, and tools, everything we offer is something we believe in and use ourselves. We don’t believe in cutting corners or selling gear we wouldn’t rely on during our own backyard cooks and when we compete in BBQ competitions.
