All SCTs come from factory with SCT diagonals, which screw into the visual backs...
If you want to use refractor style diagonals, you would either have to change the visual back to a compression ring style, or use an SCT adapter, which screws into the visual back, and then you insert the diagonal into it...
I particularly use a 2" AP visual back with compression ring, and then I insert my 2" TV diagonal into it... 8)
