If you use your grill often, you are going to encounter wear and tear on many of the components. The cooking grids are used every time you grill, so it only makes sense that they will need to be replaced. It is far less expensive to replace cooking grids than to replace an entire grill. American Outdoor Grill makes replacing components of your grill easy. This set of 3 replacement cooking grids is made specifically for AOG 36" grills. It can be used with both built-in and freestanding installations.
