G, it fit well. I let some wood chunks smoke up quite a bit when I started up. Nothing came out the bottom and not too bad out the top. Not too much lateral movement on the kettle. I did notice it fits better on the newer kettles than it does on the older kettles. I didn't investigate they too deeply though. It also fits really well on my ss performer. There are notches in the bottom to fit around the lid bale screws. I am not sure if the older style has that but it seemed to help lock it in place even more. I am very pleased with it.
