Versatile Magnetic M Kit (PRVMFMKIT) The magnetic frame set contains the frame and arm F for attaching to your Brother PR Embroidery Machine. Compatible with all Brother PR Machines 100 x 100 mm (4 x 4") embroidery area. Perfect for beginners! No catches, and no levers, just place the magnets and embroider. Embroider materials up to 2 mm thick. Reduces scratching and hoop burn damage to your hooped materials. Use with difficult-to-hoop and tubular items that cannot be hooped in traditional Clamp M hoops – tote bags, small shirts, embroidery blanks, and more! Now you can stitch on the mid and bottom parts of tote bags. Can be used without removing the base embroidery frame from the machine. Scale marks every 10 mm for easy position reference. Can be used with PR655 and above (rolling updates for legacy machines from Sept 2021). To check compatibility, visit Brother Solutions Center. Art. No. D01XJY001
