Round Base Magnet with Hook for Tool Box
These Chrome plated strong Neodymium Magnet hooks will make a beautiful addition to your refrigerator or file cabinet, and are even strong enough to pull duty on your tool box. These 12 pound rated magnets will hold the full 12 pound rated weight vertically from the underside of a thick steel surface. In a horizontal application (the side of a fridge), the strength diminishes about 2/3 due to shear forces.
