Rubber-Coated Magnetic System with Internal Thread

They are neodymium pot magnets coated with rubber. In the center, they feature a threaded insert for mounting. The rubber coating provides not only magnetic but also mechanical grip, so the pot magnet “suction-cups,” does not slip, and does not damage the surface it rests on. Ideal for holding large objects on sensitive metal surfaces—such as lights or advertising signs on car roofs (sirens, plates, etc.). Rubber-coated pot magnets with a plastic cable housing are also very popular.
