125mm [4.92"] diameter x 100mm [3.94"] tall including M14 eyebolt. 2% tolerance. Each magnet can support 130kg [286 lbs.] vertically from the magnetic face when in flush contact with a mild steel surface of equal thickness. Protective, durable chrome plated steel shell. Heavy duty M14 eyebolt with a 20mm [0.79"] inner diameter (safe working load 500kg [1,102 lbs.]). Rope is red in color, 10 meters [32.8'] long with a 4mm [0.16"] diameter and has a breaking strength of 420kg [925 lbs.]. Ideal for Magnet Fishing. These extra-large ferrite pot magnets are made of a ferrite magnet sunken in to a chrome-plated steel shell meaning that the north pole is on the center of the magnetic face and the south pole is on the outer edge around it. The steel pot increases the adhesive force of the magnets giving them an incredible hold for their size. Each magnet comes assembled with a heavy duty eyebolt that can easily accommodate a thick lifting robe or cable. An added advantage of pot magnets is that they are resistant to chipping or cracking following constant impact with a steel surface. These magnets come with a safe-handling warning; because they are so powerful they can be dangerous if not handled carefully. The magnet is accompanied by a 10-metre-long polyester rope which can hold a hefty weight of 420kg [925 lbs.].
