Steven,
The rotis are not necessarily interchangeable.
Be sure you check your measurements before you commit.
Also, Cajun Bandit sells 2 differnet rings.
One for the 22 Kettle\Cajun bandit and one that fits a Kettle\WSM.
ANd the Weber ring is not a real good fit. If had to do it again, I would go the CB.
But the Weber one works fine.
