This strong mounting magnet has become a real classic. It was specially developed for signmakers to fix and apply graphics and digital prints without any outside help. The so-called accordion technique can also be used with the SpeedMag HD. The magnetic plate has a rubber-like, abrasion-resistant coating to protect the film surface. If you want to be on the safe side and protect the film additionally, you can cover your magnets with Yellotools MagPatch self-adhesive pads.
