Lian Li Case PC60 PLUS

[apprentice25]

Good evening:
I just received my Lian Li Case. There is something that I cannot figure out. It came with two aluminum parts. I think that it is some kind of air vent. If someone has this case, and can explain to me what it is, and how to install it, it would be appreiciated.

Thanks

I narrowed down what it is. If someone with this case could be kind enough to give me assistance on how to install this, I would be great.
