It fits my Weber Searwood 600 perfectly. You have to remove grill before you install it. It is great to cook almost everything without worrying about your food falling through the grill.
I was so excited to get this. Breakfast was so much better on this and we actually haven't switched back to our grates since. I've made scrambled eggs, pancakes, bacon, burgers, steaks and vegetables and it's all come out perfect.
