Practical Design They are amazingly wonderful for their size and have innumerable uses. It is Ferrite Magnetic hook, Grade 5. Data based on scientific measurement Vertical Tension: 22 lbs Horizontal Tension:7 lbs 1. We used A3 high quality steel as the test floor. 2. After many measurements, we have obtained scientific and rigorous measurements by pulling the hook at a uniform speed on professional equipment. Several Important Factors Affecting the Tensile Force 1.Only when the thickness of the tested steel reaches a certain level, the tensile energy can reach the ideal value. 2.Only when the force is perpendicular to the contact surface can the tension reach the maximum. When the force is parallel to the contact surface, the pulling force can only reach 1/3 maximum. 3.It can not attract aluminum, copper, wood, plastics and stainless steel. 4.The farther the magnetic hook is from the material, the smaller the pull force would be. Therefore, the surface paint adsorbed by magnetic hook is also an important factor affecting the pulling force of magnets.
- MULTI PURPOSE: Perfect use for hang little gadgets, the 22lb magnetic hooks usually used for hang hats, keys, towels, but to be honest, items will slide down the walls with more than 3 lbs hanging on it.
- SMALL SIZE: We do not suggest to use this 22lb magnetic hooks for hang heavy items, though you can really feel the pull when attaching them to a metallic surface via vertical adsorption on the material surface.
- EASY ASSEMBLE: Magnetic hooks are easy to remove, they would be great in any small space to aid storage and easy accessibility, and these magnetic hooks fit in anywhere and serve a purpose that cannot be duplicated.
- ATTENTION PLEASE: Due to the power magnetism, if you want to use these Magnetic hook on stainless steel refrigerators, we suggest to put a tissue or something else between the magnet and the surface to protect the surface from scratching.
- LIFETIME GUARANTEE: Our products are extremely high quality and are checked during and after production for quality, your purchase is protected, return at any time and at any point. What are you waiting for, It is time to declutter the space.
