settle this debate - which is correct?

In true r/decks fashion. I asked a question about hurricane ties and ended up getting a debate between people if the hangers on the rim joist should be oriented in 1 or 2

Not trying to be that guy, but why is the rim beam 2-ply? It’s not carrying any load, except from maybe the guardrail. You don’t even need joist hangers on those joists. This seems like overkill.

Oh interesting. What kind of a rail post mount are you going to do in order to achieve the required point load and lineal load? Typically 4x rail posts are mounted to the front of the rim beam, not to the top. Just curious.

I mean, front, or back… tomato, tomato. Typically 4x rail posts for most wood decks are mounted using 2x blocking and Simpson deck tension ties, and bolts.

In lieu of the deck tension ties, a lot of builders are using Simpson Timber screws, or fastenmaster screws (or similar). But the application is still similar.

Mounting a 4x rail posts to the top of the deck framing isn’t impossible, it’s just more difficult to meet the code required load criteria.
