This was a perfect fit for my four burner flat top Grill Blackstone I replaced it with the stainless steel because it is easier to clean and better only issue is I had to make a few modifications to make it lock on the grill preventing it from sliding off and some modifications to the grease pan because on the original it went in the back and on this one it is on the front I could use some action reinforcements to prevent it from warping during high heat but other than that I am completely satisfied with it
