⭐ Complete mounting kit, ready to use right out of the box. Embedding the neodymium core in a steel housing significantly increases the power of the magnet and its protection against breakage as a result of a violent impact.

⚡ Note: screws should be tightened sensitively. Despite the steel casing, the neodymium core is a brittle material, resembling ceramics. Tightening the countersunk screw too hard will act as a wedge and can cause the magnet to break from the inside.

What sets our product apart is its targeted magnetization. Half of the magnets in the box (4 pieces) have the opposite polarity on the exposed side of the neodymium than the other four. Thanks to this, the set offers you three variants of use:

➡ Option 1 (Magnet itself): The simplest and most popular application. You screw the magnet to the wall, bookcase or wooden shelf and directly "stick" objects made of metal (tools, keys, bits, knives) to it.

➡ Option 2 (Magnet + Magnet): You pair two magnets together from the set. Thanks to the different poles, they will perfectly connect with each other. You mount one magnet on a structural element (e.g. frame, jambs), and the other on the moving element (e.g. doors). The arrangement of two magnets increases the range of attraction ("catch" from a greater distance). It is an ideal solution where the door or flap may not close perfectly and require a stronger "tightening" from a distance (up to 3-4 mm).

➡ Option 3 (Magnet + Material + Magnet): You press the material (e.g. mosquito net or thin fabric), inserting it between two magnets: the first (screwed) and the second (unscrewed) with opposite polarity. Loose (unscrewed) magnet automatically and precisely centers (it will jump perfectly opposite the screwed magnet pressing the material in between). Note: each layer of material acts as a distance and drastically reduces the power of the magnet, so this method will work only for light and thin materials (up to 3-4 mm).

Magnets have a screw hole with the so-called. chamfering (cone-shaped). Thanks to this, after screwing in the included screws, their heads perfectly match the surface.

Neodymium magnets have a powerful attraction force. Taking care of your comfort and safety, each magnet in the box has been separated from the rest by a special plastic spacer. This makes it easier to separate them freely before assembly.

Thanks to the special construction, the included screws and the polarity of the magnets selected in pairs - you get an extremely versatile mounting system. The set is perfect for:

✅ Space organization (magnetic handles): screw the magnet to a wall, bookcase or other surface and create your own hanger for metal objects. Directly to the magnet you can easily "stick" knives in the kitchen, keys in the hallway or tools in the workshop and garage (imbuses, bits, screwdrivers, pliers).

✅ Stolarstwo: as invisible locks and latches for wooden boxes, boxes and furniture.

✅ Home: for mounting mosquito nets, curtains, as well as hidden inspection doors (e.g. pipe grilles, counters in the bathroom).

✅ Workshop and garage: to be screwed to a wall, shelf or rack to hang tools, keys, bits.

✅ Automotive / Motorhomes: to securely lock cabinets and drawers while driving.

Many sellers give inflated values. We play open cards and educate our clients. The maximum lifting capacity (12 kg) is the force measured in laboratory conditions with perpendicular detachment from the steel plate with a thickness of 2.0 mm.

Remember that in everyday use, the strength of the magnet is influenced by two key factors:

1 Thickness of the metal surface: the thinner, the smaller the tearing force of the magnet (see Table-1 in the graphic).

2 Direction of force action: if the magnet is affected by a sliding force, the weight maintenance is determined not by one (as in the case of detachment), but by two forces: pressure force (equal to the detachment force) and friction force depending on the friction coefficient of the magnet by a given type of surface (Table-2). On slippery, polished steel, the magnet will slide off much easier than on a rough, matte surface of the same thickness.
