Ideal self adhesive backings for our magnet cups and washers, these high-friction discs are made of a soft, non-marring acrylic material.

Cut slightly undersize (0.025") to the outside dimensions of our magnet cups and washers, they have a high-tack adhesive backing capable of withstanding high shear loads, even at elevated temperatures (to 140°F). Made in USA.
