ATR attaches to neither. This is at least the section I have pulled out before.

One my fellow Designers is looking for an FM approved Threaded Rod . I had this come up a few a years ago and if I recall the actual threaded rod is not required to be listed . I believe I have the code section written down at my home office , but I won't be able to get to it till the end of the day and well I have no patience to wait . Does this ring any bells For anyone ?
