If you haven’t been hiding under a rock, you should know that Magneto is the mutant foe of the X-Men who has the power to control magnetism. A similarly named tool uses the power of magnetism to hold your tape measure to your belt — making it easier to remove and replace than the standard tape measure clip.
The polycarbonate Magneto clips to your belt like a tape measure would. You remove the clip on the tape measure and replace it with the included adapter plate. Once it’s on the tape measure, the adapter plate locks into the Magneto with an audible click, so you know it’s secure. The magnet is recessed into the plastic to help prevent the tape measure from getting knocked off accidentally.
The Magneto magnetic tape holder runs about $13. If you need an extra adapter plate it’ll only run you an extra $3.
