Question about the rack structure

Hi there,

I recently got my hands on a very cheap FANTEC TCG-4800X07. Now I wonder what is the purpose of the two things I highlighted in red in the pictures. Any ideas ?


I guess that it might be something obvious, but, you know, I have to start somewhere !

Second shot looks like something to ground to the case.

They are just retention mechanism for PCI/PCIe cards.

Good call, at second look it looks to be directly across from the first picture. I didn’t see that first go round.

I concur. Server grade expansion cards can be very long so you’ll sometimes see these types of retention mechanisms.

Thank you very much ! I couldn’t guess that !
