The fence consisted of wooden posts

[99bottles]

This is a sentence I'm writing.

The fence consists of wooden posts, with steel wires between.

Is the comma between posts and with needed?

 

[emsr2d2]

No. I'd end with "between them" or "in-between".

 

[Tdol]

Or just with steel wire. I can't see any other way the wire would go with fence posts.
