This article is remaining stock. As soon as the inventory is sold, it will be taken out of the assortment.

This suction cup with a 40 mm diameter is screwed together with a pot magnet with an internal thread on the back side. You can use it to temporarily hang up heavy ferromagnetic objects such as a large metal sign.

Please note:
  • Surface requirements for suction cups: The surface needs to be completely smooth and clean (free from grease and dust) before attaching the suction cup, which needs to be clean as well.
  • Don't put suction cup magnets in places with high temperature and humidity fluctuations, which can quickly lead to a loss of suction power.
  • The embedded magnets will start to rust in wet surroundings such as the kitchen or bathroom at some point, so you will have to exchange them.
