Well, you certainly wouldn't be using threaded rod and you will need to be sure you can connect to I-Beams per building codes where you are. They aren't always allowed to be fastened to. Sometimes you have to go directly to the slab above.

Proper hanging is typically done using 1.5" NPT and a rated mount for it.

I might reach out to Chief for this endeavor. But, I'm not sure how much they can help with the actual mounting. Beyond that, I would go to a commercial AV company for the job as they will know what they are doing locally.

Looks like you got the right gear for the job. Chief is a gold standard by which others are measured against and is pretty much the only brand we use in our commercial integration. I use their projector mounts almost exclusively in my residential jobs as well.

For cheaper residential mounts, I often go with less expensive mounts, but at the end of the day, when quality and performance matters most, I go to Chief. I recently put a 85" Sony (120 pounds or so) onto a articulating mount... by Chief.

I'm sure it will last you for years, and I really like that NEC display.
