I designed it for the Ikea Lack model table. I used it to close open printers. You can use it on all kinds of surfaces. I made a setup for myself with glass on three sides and wood on one side. I used it for glass surfaces. I attached a neodymium magnet to the glass surface with hot silicone and screwed these pieces to the table. I have used it this way for years without any problems.
You've got the points. :)
