To help insure that you get the correct replacement parts for your Costco grill, we highly recommend that you measure your original parts and compare them to what we have listed below. This is best done with the parts out of the grill. Verify your model number. The information shown below for Costco grates is the latest we have and believed to be accurate.
NOTE: For rock grates, the critical dimension is front-to-back. Grates can be an inch or so narrower (side-to-side) and still be fully functional. Heat plates/Flame Tamers can also be narrower as long as they are wide enough to cover the burner.
