SKU 9450 is a 20 mm (0.79 in) N35 neodymium fabric / curtain magnet with a removable button. It is designed for compact magnetic closures in curtains, drapery, fabric panels, and other soft-goods assemblies where a concealed or low-profile magnetic closure is preferred over a conventional mechanical fastener.

For curtain applications, two units can be positioned so opposing poles help draw fabric panels together. Check polarity before final installation. Fabric, liners, pockets, and other nonmagnetic layers create an air gap, so usable closure force through the finished assembly will be lower than a direct-contact pull-force value.
Do not drill or puncture the magnet itself. Sintered NdFeB is hard and brittle. Use the removable-button feature or an appropriate pocket or enclosure instead. See the 20 mm Sewing Magnets — Pack of 2 for another sew-in style and browse Fabric / Curtain Magnets for related products.
For alternate sizes, sew-in formats, enclosure concepts, or production quantities, compare the Neodymium Magnet Grades Chart and submit the Magnet RFQ Builder.
