Square Corner Magnetic Shuttering Magnets are a magnetic fixing system designed specifically for the precast concrete industry, particularly for corner shuttering applications such as door and window frames. They utilize high-strength neodymium iron boron (NdFeB) magnets protected by a metal housing and quickly operated via a simple on/off button. With a range of holding forces from 500 kg to 1,800 kg, they can meet the needs of projects of varying sizes.
