I'm not sure if I’ve seen the Krone connection blocks before. Are they primarily a European device?
How do those differ from the 110 punch down blocks and jacks?

As Hal rightly points out, 110 and Krone punchdown tools are
not interchangeable!
Here are the Krone terminals on the back of one of our standard line jacks:
