Mirka pad saver discs are an excellent idea to extend the life of the backing pad on your LEROS sander. They fit between the sanding pad and the abrasive disc as a sacrificial disc. The pad saver does what it says: minimises wear of the sanding pad and helps prevent heat build-up on the hook and loop of the sander's original pad. Simply peel off and discard when it eventually becomes worn. When using Abranet® abrasive discs a more positive attachment to the sanding pad can be obtained with the use of these discs.
