These 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 centre 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. IDEAL FOR RETRIEVAL & RECOVERY. Specially designed for recovering and retrieving large ferrous items, magnetism is concentrated on one face to provide the maximum holding force. EXTREMELY STRONG RARE EARTH MAGNET. Each magnet can support 60kg vertically from the magnetic face when in flush contact with a mild steel surface of equal thickness. RESISTANT TO CRACKING & CHIPPING. An advantage of pot magnets is that they are resistant to chipping or cracking following constant impact with a steel surface thanks to their protective, durable chrome-plated steel shell. HEAVY-DUTY EYEBOLT INCLUDED. Each magnet comes assembled with a heavy-duty eyebolt that can easily accommodate a thick lifting robe or cable. SPECIFICATIONS. 125mm diameter x 100mm tall including M14 eyebolt. Heavy duty M14 eyebolt with a 20mm inner diameter.
