RCI Modular Tonneau Adapter

Hello everyone, I am just wondering if anyone is using, or previously used the newer style RCI Tonneau brackets for their bed racks.

These ones here

I'm having a hard time finding photos/videos of them installed. I have only come across the older style brackets.
I'd like to know how it mounts and what it looks like inside the bed for tonneau cover mounting purposes before I purchase these.

If anyone has some photos of these it would be greatly appreciated.

Thank you!

 

This is the first I've seen this, but in the compatibility list for the Bakflip MX4 it says "static cover only". Does this mean you can't fold up the tonneau?
