Horizontal and Vertical bends are only 24", 36" and 48". There are no 12" radius bends - used more than any other radius.
Mike, I just want to confirm that you still need to design with 12" radius fittings since these seem to be discontinued.

12" fittings are still in the catalog that you reference see attached. I can check with our rep, but I don't believe that they would discontinue 12" radius since that is what is used must except when you have larger diameter cables that require larger bending radius. See page FTS-4. "Series 2,3,4 & 5 Fittings.

To add 12" bend radius to the fittings, please replace the files in your dataset(s) with the ones in this zip file.
