Metal fence holder for wooden fence

Hi, does anyone know what this type of holder is called

Regards

Do you mean the posts? Steel rectangular tube hot-dip galvanized.

Tip on the side. Find out whether something like this is allowed where you are.

Thank you, they have an overlap at the bottom both in the front and back where they are drilled into the curb. Why should something like that not be allowed?

You can't see that in the photo. I meant the height and the type of fence.

I would like the height to be 1.8 directly on the boundary of the neighbor, I would take over half, there should be no problems with that in Bawü

Some development plans are not so flexible there. My neighbor also simply built a 2 m high privacy screen. That was OK with me. When I once inquired at the building authority about a boundary construction and mentioned in passing that the neighbor had installed a 2 m privacy screen, I was told that something like that is not permissible. But where there is no plaintiff, there is no judge.
