Add a super-strong hook anywhere you have a metal surface! Great for holiday decorations, lockers, shops tool benches, refrigerators more! The rotating swivel hook provides freedom to accommodate items of different shapes sizes. Mount to any magnetic surface: Storage shelves, cabinets, doors, vents ducts, etc. Magnets are strong enough to pinch skin, please be careful! These are not toys. This is definitely not your average, low quality magnetic hook! Spigotware Swivel Magnet Hooks are serious magnetic tools that pack a punch. We use extremely strong grade N35 Neodymium magnets and pair them with a chrome plated 180 degree swiveling, 360 degree rotating hook. Magnet strength increases based on the thickness of the metal it is attached to. Mounted to a vertical plane (i.e. a wall), our magnets will hold up to 15 pounds. From a ceiling, then can hold up to 50 pounds. Each magnet includes two free micro magnets.
