Mighty Hook is introducing a new re-usable high temperature silicone disc combined with a high temperature magnet. This magnetic disk is used to mask ferrous products and can withstand 500°F. It’s advanced design seals around edges to insure quality masking, a tight seal, and leaves no marks. What sets it apart from standard green discs is that it is re-usable and much easier to place and remove than die cut discs. Plus, you get two different diameters in one disc. Three sizes are available.
