Expensive and Weak

they don't hold anything substantial unless you screw them in. Defeats the purpose of a magnet.

Magnetic hooks
Color: Black3pro
They are nice magnets but don’t hold much weight and slide down the metal wall. They are good for small lighter items. Really don’t see them as heavy duty.
