On the other end, there are 3 options, a flat ROUND flange adapter, a rectangual flange adapter for ceramic pit, and adapter for Weber.
My last reply was wrong, there is not square adapter with 4 holes(as fan adapter A),
please check this picture, and let me know which you need. I guess that you shall use the rectangual flange for ceramic pit. If so, I need the size
Yes,, the rectangular one, same size as fan adapter A, which I believe is 5cmX7.5cm thanks
