It's been a while since I have used those, but over the years there have been several jobs with different types of wire/cable displays.
The only one I have pics of (and they are really bad) was the very first job I had to rebuild after the fire, so August of 19. There were 6 of these units. The went into information centers of city Metro-Parks. I had just finished them, had them prepped to be delivered the next day.
The one I have the installed pic of, is very close to my house. I stopped by to do a punch-list item for that job, since it was on the way home. The have upper and lower mounting points, plus some stand-offs in the middle to keep the glass shelves from wobbling.
The ones in the center section have acrylic holders for pictures. They are just a folded sheet that is closed at the bottom, held by the sides and the images can be lowered into them.
It's kind of an erector set of a million parts. You have to cut the cables to a fairly exacting length and crimp a stop onto them, which takes some special tools.
Again sorry for the bad pics. Sadly, I have quite a few project pics that look like that, before replaced that phone. There are years worth of jobs that I don't have anything, since it was before decent phone cameras. I had a little digital camera that I took in once in a while, for bigger things. It just wasn't as easy as it is now.
