You need a newer catalog. All of them are illustrated in the latest

It's the same bracket with longer arms. Wimpy? Well, it IS for 25G so
it's not too brute.

These are "universal" brackets, that is - they're drilled for 25G and
45/55G. My decision of which one to use has to do with how much distance from
the wall is needed. If I need more than 36" (and sometimes I do), then I use
2x4 spacers at the wall.
The 25G versions are fine but the other ones are more heavy duty. They
are HEAVY so if you think you need them - go nuts.
