Safety notice

NdFeB magnets are hard and brittle. Especially with the thinner, narrower dimensions/due to the higher grip strength, they can easily break or split! Therefore, the impact of the two magnets, as well as external, mechanical impact or pressure load, should be avoided! A safe distance between magnets is 30-50 cm. When turning the magnet with wood screws, it is very important not to overtighten.
