--63mm x 50mm x 55m high\n\n--Switchable magnetic base in a shallow 'V' shape for gripping round surfaces of at least 80mm diameter\n\n--Simple toggle switching mechanism\n\n--Each magnet can support a steel weight of up to 70kg vertically from the magnetic face when in flush contact with a mild steel surface at least 6mm thick\n\nOperated by a simple toggle switch, switchable magnets are ideal for quick-release jigs, fixings and lifting applications where it is necessary to be able to turn magnetism on and off. Perfect for industrial environments each magnet can lift a steel weight of up to 70kg when in flush contact with a mild steel surface at least 6mm thick. If more holding force is required, a number of these switchable magnets can be used together. Each switchable magnet has an M8 threaded mounting hole.
