Best used in a shear position, rubber-coated pot magnets have a superior slide resistance over regular magnets due to the increased friction generated between a rubber and smooth steel surface.
Corrosion is the most common reason for a failing magnet. By adding a rubber-coating to a magnet you increase its resistance to corrosion and what’s more they are safe to use on easily marked surfaces without scratching. Typical applications include suspending outdoor cameras, heavy-duty gate and door latches, hanging signage and mounting sensors.
