Magnet - Neodymium disc 10x4mm
M6 Nylon Locking Hex Nut
Prepare four assemblies
Tip: Use a drop of super glue to prevent the magnets from coming off over time.
Please verify the magnet polarity in relation to the magnets on the door panel. If the polarity is inverted, the magnets will repel each other instead of attracting.
