Ceramic Magnets
Ceramic magnets resist demagnetization better than other magnets and are an economical choice.
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.

Ceramic Magnets with Unthreaded Hole
Ceramic magnets resist demagnetization better than other magnets and are an economical choice. Slide onto a rod or use a bolt or screw to install.
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.

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.

Encased Ceramic Magnets with Threaded Hole
These ceramic magnets resist demagnetization better than other magnets, and have a metal case to protect the magnetic material. They resist temperatures up to 175° or 245° F.
Magnets with a steel case have a more concentrated and focused magnetic field than magnets with an aluminum case.
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.
