Can this holder be used to insert a filter before the MaxBright II binoviewer connected to a Prism diagonal T-2/90º 32mm? Is anything else needed?

The description of this filter holder says it has a continuous male T2 thread on the outside, but the image looks like it has some kind of stop ring (maybe midways). According to the specifications, the outer diameter is 46mm, much more than the 42mm of a T2 thread, which suggests that there is really some kind of stop there.
Which one is right: is there a continuous male T2 thread from one end to the other, or is there a 46mm stop separating two male T2 threads?
