It's Better than the pictures! I got the 1/2" thick version, The 2 sides are formed from the whole plate (Solid NO WELDS) and the bottom (full welded corners) attached points strip is also formed with 'sharp' cutouts for connect pins. The top "angle rail" is full welded at the corners and has very clean 2" long welds spaced across the top gap, these are spaced at the contact points respectfully. IT Fit PERFECT! The carboard wrapper barely survived but made it to destination (The thing is Heavy). I like the 1/2" thickness, so I can drill & tap attachment holes for many future built attachments! It has the GUTS to handle them. I will try to comment more on that.
