Hackers Help: What’s the name of this shelving system?

adjustable shelving system

I’ve had this versatile shelving system for years. A friend is trying to find it online. Can anyone help me with the name?

The latticed metal frames can be set into the wall however one likes, the only limit being how long your simple wooden shelf tops are.

4 simple hooks are screwed into the shelf bottoms allowing them to be easily adjusted/readjusted.
