Supermagnete Waterproof magnet

The rubber-coated disc magnet has a diameter of 16.8 mm and a height of 9.4 mm, providing a holding force of approximately 3.7 kg. Thanks to its rubber coating, it is waterproof and can be used permanently outdoors or in water. The coating protects delicate surfaces such as whiteboards or glass magnetic boards from scratches.

The rubber coating may leave dark streaks if you rub the magnet strongly against a surface. However, these can be easily removed with a damp cloth.

Holds on the ceiling (force acts perpendicular to the magnet's contact surface): approx. 3.7 kg
Holds on the wall (force acts parallel to the magnet's contact surface): approx. 1.1 kg

The specified force is achieved when the magnet is placed directly on a flat metal surface. To maintain its strength, avoid collisions with other magnets or impacts (e.g., with a hammer).
