Heat Plates
Critical Dimension: The critical dimension for heat plate fit is determined by the way the plate mounts in the grill housing. Most plates mount front and back, so for these plates this dimension (depth) is critical. A significant minority of plates, however, mount left and right. For these plate, the width dimension is critical. We list heat plates in descending order of the critical dimension, so to find a replacement part, you must first make note of how the original part mounts in your grill, front and back or left and right.
As a general rule, a replacement heat plates must be within three sixteenths of an inch (0.1875”) of the original part in the critical dimension to fit correctly. You should measure your grill to make sure the replacement plate will fit before buying a part with a critical dimension different  from that of the original part.
The other dimension of a heat plate is much less critical. A replacement can be a few inches narrower or shorter than the original and still be useful.
