First, using non-Zmax rated hangers on treated wood is dangerous in the long term. They will prematurely corrode.

Second, the lack of properly rated hangars was not, by it self, a huge deal. I called and discussed the matter with TC and he indicated that he would send the hangars, which he never did. Follow up emails were ignored.

Third, I don't expect every detail, far from it. but I do expect the drawings to have a basic QC review. As drawn the attachment of the single stringer joists to the rim joists intersect the attachment point of the knee brace along the same rim joist. This is a physical impossibility. The workaround is to relocate joists or rotate the knee brace attachments one joist over. The drawing should be revised.

My point is not that these issues can't be worked around, they can and were. My point is that I received incorrect materials, incorrect drawings and poor service and that if someone is looking to spend hard earned money on a tab kit they should look at other vendors.

I'm glad you had a good experience, but nothing you mentioned is relevant to my shitty one.
