Magnetic neodymium insoles with an integrated string on one side are threaded with an “M” so that they can be supported. As magnetic treads they function similarly, with the metal container surrounding them protecting them from breakage and vibration, while enhancing their adhesive magnetic force when adhering to metal surfaces. The metal container changes the magnetic flux and thus increases the strength. Therefore, the adhesive force acts on one side of the magnet. Magnetic treads with a built-in dowel, on the side of the magnet, have a higher pulling force than treads with a milled hole because they have a higher mass due to the absence of a hole. Combined with our safety nuts they are the ideal retainer for small to very heavy metals. The maximum weight they can lift is 160 kg and they can withstand temperatures up to 80°C.
