Pad saver
Mirka's pad savers are designed to protect the backing pad from wear and tear, when sanding aggressively and continuously
with net products. These cost effective pad savers, placed between the backing pad and the sanding disc, should be
changed regularly. The pad savers prolong the life of the backing pad.
