This 20mm x 4 mm disc is one of our most popular products, its size and strength make it an incredibly versatile magnet. Discs such as this make great closure devices when stitched or seamed into fabric or other flexible material such as shade cloth, insulation, curtains. Depending on the thickness and weight of the fabric, these discs can be inserted inside a seam and be coupled with another magnet or steel in the corresponding surface/material to create a reliable and secure closure.
These magnets have also been adopted by Fashion Designers who like a simple yet effective way to hold complex and voluminous fabric arrangements in place on the catwalk. If you have ever wondered how those bizarre high fashion outfits are held in check, magnets are the solution!
They are also used for many industrial and manufacturing applications such as metal separation, pharmaceutical stirrers, metal detectors, tool holders,
