It's actually just one 6'x6' panel that I'm installing and while I've read up a bit on the internet, I'd like to get input from people that have actually done it. This is the one I'm eyeing. As far as parts, I know I need the 6'x6' panel, the two end posts, post tops, rail brackets, screws, etc. I believe I also need rebars? Do you put the post first and then the rebar inside? Besides filling the hole with concrete, do I fill up the hollow post with concrete as well? Up to what height? The instructions that I've read talk about rails like a separate piece but the panel that I want to buy seems to have the rails already installed to the panel. How was yours? Any help will be deeply appreciated. Thanks.
