The posts come in different sizes, 3 and 5 feet I think. I use the 3 foot version but those are incorporated into the fence itself.
I like them because they're a sturdy base to tie the uprights to. And the cross pieces can be set to whatever height I want them and can easily slide them up and down to where I need them.
