Faced with very old door closures in my kitchen, we had to find a "practical" solution to keeping the doors closed. I did not have to dig pitches for articulated hinges as there is everywhere now. I turned to magnets. These magnets with their milled inner hole seemed all shown me. With a pull of almost 1 kilogram force (!), They are actually at the level of work required. I fixed on the door a small plate made of galvanized steel 2 * 1 * 0.15 cm so that there is some material to magnetize, of course. On the door jamb, a small square metal (one side of the square: 2.5 cm, 1.5 cm across the width of the metal plate. 1.5 cm and thickness: 0.15 cm). I screwed the long side of the bracket on the door jamb and on the short side of the bracket, I screw the magnet through a 3mm diameter screws with metric countersunk screws (to enter into the hole the magnet) and I place a thin cardboard washer behind. Do not over tighten the screws as the metal of the magnet is "relatively" fragile, hence the cardboard washer. After placing the elements on doors and door jambs, doors are finally closed. And believe me, with a magnet "pulling" to one kilo, must be forced to open the door.
If more force, we can fix a magnet on the door instead of the metal plate. It doubled the magnetization effect. It takes almost two hands to open the door. I practiced and to close a toolbox. It keeps no problem.
These magnets are very small. When you hand them, one can doubt their effectiveness while first. But once we test ... the result is the height. This has nothing to do with the magnets sold in supermarkets!
