Our gun holder is completely covered with a thick layer of soft rubber, which guarantees full safety of the weapon's surface. Rubber also acts as an anti-slip, preventing the weapon from sliding under its own weight.
Holding force is sufficient for the weapon not to fall even during shocks (e.g., in a car). The design guarantees quick access while maintaining a sure, safe grip.
Thanks to the flat profile, it is easy to hide and discreetly mount. Mounting is done using the included screws or very strong double-sided tape (on smooth surfaces).
It is compatible with any weapon that has a steel slide, barrel, or frame. It also works with full steel magazines, tactical knives, and flashlights.
In Poland, the method of carrying weapons is defined by appropriate regulations (weapons should be under constant control and as little visible as possible). The holder is ideal for S1 safes, where the way the weapon is arranged is not strictly imposed, as long as it is inside.

Pros as well as cons of neodymium magnets.

Benefits

Besides their durability, neodymium magnets are valued for these benefits:
  • They do not lose strength, even over nearly ten years – the decrease in strength is only ~1% (based on measurements),
  • Magnets effectively resist against loss of magnetization caused by external fields,
  • A magnet with a shiny gold surface has an effective appearance,
  • Neodymium magnets deliver maximum magnetic induction on a small area, which ensures high operational effectiveness,
  • Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
  • Possibility of detailed modeling and optimizing to precise requirements,
  • Fundamental importance in advanced technology sectors – they serve a role in HDD drives, electromotive mechanisms, precision medical tools, as well as technologically advanced constructions.
  • Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which enables their usage in small systems

Disadvantages

Drawbacks and weaknesses of neodymium magnets and ways of using them
  • At very strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
  • NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
  • They oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
  • We suggest cover - magnetic holder, due to difficulties in creating nuts inside the magnet and complex shapes.
  • Health risk related to microscopic parts of magnets can be dangerous, if swallowed, which is particularly important in the context of child health protection. Furthermore, tiny parts of these products can be problematic in diagnostics medical in case of swallowing.
  • With mass production the cost of neodymium magnets is a challenge,

Lifting parameters

Maximum holding power of the magnet – what it depends on?

Holding force of 5.00 kg is a theoretical maximum value conducted under specific, ideal conditions:
  • on a plate made of mild steel, effectively closing the magnetic flux
  • whose thickness reaches at least 10 mm
  • with a surface free of scratches
  • without the slightest insulating layer between the magnet and steel
  • under vertical force direction (90-degree angle)
  • in stable room temperature

Determinants of practical lifting force of a magnet

Real force is affected by specific conditions, such as (from most important):
  • Gap between magnet and steel – every millimeter of separation (caused e.g. by veneer or dirt) diminishes the pulling force, often by half at just 0.5 mm.
  • Angle of force application – highest force is obtained only during pulling at a 90° angle. The shear force of the magnet along the surface is typically several times lower (approx. 1/5 of the lifting capacity).
  • Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
  • Plate material – mild steel gives the best results. Higher carbon content lower magnetic permeability and holding force.
  • Surface quality – the smoother and more polished the plate, the better the adhesion and stronger the hold. Roughness creates an air distance.
  • Thermal factor – hot environment reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.

Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under attempts to slide the magnet the load capacity is reduced by as much as 75%. Moreover, even a small distance between the magnet and the plate decreases the load capacity.

H&S for magnets
Safe distance

Very strong magnetic fields can erase data on payment cards, HDDs, and other magnetic media. Keep a distance of min. 10 cm.

Shattering risk

Neodymium magnets are ceramic materials, which means they are prone to chipping. Impact of two magnets will cause them cracking into shards.

Pacemakers

Warning for patients: Strong magnetic fields disrupt electronics. Maintain minimum 30 cm distance or ask another person to handle the magnets.

Immense force

Exercise caution. Rare earth magnets act from a long distance and connect with massive power, often quicker than you can react.

Do not give to children

Neodymium magnets are not intended for children. Swallowing multiple magnets can lead to them connecting inside the digestive tract, which poses a direct threat to life and necessitates urgent medical intervention.

GPS Danger

An intense magnetic field interferes with the functioning of magnetometers in phones and navigation systems. Keep magnets close to a smartphone to prevent breaking the sensors.

Skin irritation risks

Studies show that nickel (standard magnet coating) is a common allergen. If your skin reacts to metals, refrain from direct skin contact and choose encased magnets.

Maximum temperature

Avoid heat. NdFeB magnets are sensitive to heat. If you need resistance above 80°C, ask us about HT versions (H, SH, UH).

Bone fractures

Danger of trauma: The attraction force is so immense that it can result in hematomas, crushing, and broken bones. Use thick gloves.

Dust explosion hazard

Mechanical processing of neodymium magnets carries a risk of fire risk. Magnetic powder reacts violently with oxygen and is hard to extinguish.
