This white rubberised magnet system with a diameter of 88 mm has a countersunk hole and can be fastened with a countersunk screw. Underneath the rubber coating is a steel plate with 12 embedded neodymium magnets. These magnets are aligned with alternating upward-facing north and south poles. The rubber casing made of TPV prevents scratches and provides slip resistance. It also protects the magnet system from occasional moisture and splash water. During permanent outdoor use, however, rust can form. Our ferrite pot magnets, on the other hand, are rust-proof.
