Product description

Magnetic holder with holes for M3 screw. The mount consists of a neodymium magnet and a steel pot that concentrates the magnetic force into a small space on one side of the magnet. Thanks to this, the mount can also hold heavier objects and is suitable as both a vertical and horizontal holder. Since all the magnetism is concentrated on the surface of the active side of the mount, the force drops off sharply with distance and the mounts have almost no effect on more distant objects. The back of the mount is only very weakly magnetic.

Under ideal conditions, a 40×13.5×5 mount can hold appr. 17 kg of steel if it is at least 5 mm thick, touches the mount with its entire surface and hangs from it (i.e. the mount points the active side vertically downwards and pulls the steel object upwards). It takes much less force to slide a metal object off a mount than to pull it off. If the mount is fixed to the wall (not the ceiling) and objects are placed on it from the side, it can hold 4 kg.

All mounts have the north pole on the active side (thus they repel each other).
