I made a styrofoam board for that purpose and put 4 strong pot magnets type CSN-32 on it. This way, I can attach it to the metal cellar window. I attached two handles to the styrofoam cover, which makes it easy to remove. Thanks to the pot magnets, the cover attaches perfectly to the metal window.
Note from the supermagnete team: Our CSN magnets are not suitable for permanent outdoor use, because they will start to rust over time. An alternative could be 4x CSF-60 made of ferrite.
