Ahh, patch bay labels... always a fun discussion. 🙂
I'm not familiar with the Behringer patch bays, but I'll assume there's space under every point for some kind of labeling.
My method, while certainly not glamorous, gets the job done, although not as conveniently as a template.
If you have access to a label maker, or can spring for one (there are models by the company Brother that are fairly inexpensive these days).
Fill it with white tape, choose a font size that will fit in the space provided on the patch bay, and make your own. You'll need to cut the labels to fit (which is tedious, to say the least), but the end result is very professional looking.
Just an option...
