Specifications: maximum pulling force: 160600 kg; diameter: 48136 mm. Material: Neodymium magnet; Rope meters: 20 meters (the color of the rope and the gloves is random). Features: Pulling force will be maximized when pulling vertical direction with surface magnets. The pulling force will be influenced by many factors: the material of the material, the effective contact area, the smoothness of the surface, the pulling direction, the temperatures, the type of material, the thickness, the flatness , friction levels, etc.), its quality (e.g. deli.very rust), its size (thickness plus total area), etc. The large magnet is extremely powerful and should be handled with care to avoid injury and damage to the magnets. Fingers and other body parts can be severely pinched between two attracting magnets. Strong magnetic attraction and easy to carry. Package content: 1 magnet, 2 eyebolts, 1 rope 20 meters, 1 pair of gloves.
