This is a very simple pre - set up of 15 parametrical fences. All Geometry Nodes, all customizable. Possibilities are unlimited, and It's way more usable and solid in workflow than the previous array curve modifier.
Version created with Blender 3.3. It works at 3.3 +
Observation: If you want to use in previous versions, I can't guarantee It will work as expected.

Have fun!
