I'm sure everybody knows the trick where if you change the surface that the spiders are climbing, they get stuck and can't go any higher.
The vanilla example has iron bars in a stone brick wall.
Microblock strips are just vanilla with a better look.
This though just prevents them from climbing higher then the iron bars. It's useful in a wall at the 3rd or 4th high block in a wall to keep them from jumping up and getting past it.
This isn't a block that prevents spiders from climbing on...
