I am looking to start providing and installing post and panel. I know you can buy a kit on Grimco and from others for a couple hundred bucks. This looks like something I can get the parts from my local home depot (pressure treated wood with a vinyl sleeve). The question is for a 4x4 and 4x8 is ACM 3mm the standard? How do I attach the board to the posts? Do I leave 2 feet below and 2 feet into the ground? This is for a construction site to stay about a year.
