Reply to comment by theeeggman in Need to hang something from ceiling and unsure what lumber to use by me-chewbacca

Based on your answer I got the impression that the drawing I did is so bad that it might be giving the wrong impression on where I plan to lay the 4x4/2x4.

My plan is to lay it on top of the joists, not at all connected directly to the roof structure. Once laid down, I would put the insulation on top of it again. It would be flush with the ceiling.

Does it make sense? If not, what "four anchor points on the two trusses" are you referring to?

I think I understand what the plan is. I just cant tell how the joists are fixed to the studs or rafters (having a hard time with the perspective). All I can see are the metal plates that, I assume, are just reinforcements. So then I am asking how are they fixed tot their crossmembers? If they are strong enough to support the weight then my next thought is how long of a span is that? If it’s several feet then I would not want to center it on the joists. The final question is “after unstallation, what if someone were to hang on it? Would it still hold?” I’m kinda imagining you’re looking to install a heavy bag.

That metal is just the framing from the underneath drywall work. Not structural at all.

I am not sure how long is the span because of all the insulation but based on the portion I was able too see I have an impression it's pretty long.

I will try to take better pictures to see if it helps.
