I believe the piece you asked about is for the lips on either side of the top where you can pick up the unit with a skid-steer. UPDATE: I'm wrong. I can't place any 2" thick flat. It is probably 2x2 angle.
Thanks Aidan! I'll update the BoM page if and when I get to that point during my replication.
