gator magnets

They use a patented "Easy-off" release mechanism. To attach: place the basket against the steel, close the lever, then load the basket. To remove: lift the lever to disengage the magnet and lift the basket away.

The listings specify the baskets are made of steel and state "No Surface Treatment" as the finish.

Descriptions list common steel surfaces including toolboxes, storage cabinets, refrigerators and freezers, steel doors, work benches, washers and dryers, and lockers.

They suggest storing loose garage and workshop items such as spray paints, bug sprays, cleaning supplies, adhesives, tapes, paper towels, and similar supplies used in garages, workshops, laundry rooms, or sheds.
