About Magnets

Encased Ceramic Magnets with Unthreaded Hole
A case protects the magnetic material. Steel cases also concentrate and focus the magnetic field. Ceramic magnets resist demagnetization better than other magnets and are an economical choice.
A keeper covers the poles to preserve the strength of the magnet and protect it from attracting metal during storage.
Warning: Maximum pull ratings are based on direct contact with rust-free and unpainted iron plate. Variations in material condition will significantly reduce these ratings. Do not use for lifting over people.
