This strong magnetic hook has a white powder-coating. The coating is applied through an electrostatic process and is free of harmful substances. Thanks to its colour, the magnetic hook is inconspicuous when mounted on white walls or ceilings.
Please note: The full adhesive force is achieved when the ferromagnetic counterpart is smooth and of sufficient thickness and when the pot magnet makes direct and full flush contact. Pot magnets already lose much of their adhesive force at a distance of only half a millimetre to the ferromagnetic surface. This characteristic is more pronounced in pot magnets than in other ferrite and neodymium magnets. You can find additional fascinating information on our FAQ page about pot magnet features.
