The protective pad protects the grinding plate / grinding shoe of your sanding machine or sanding block from damage and wear. The protective pad is attached between the grinding plate and grinding wheels using Velcro. The protective pad should be changed regularly to prolong the life of the grinding plate.
Mirka's pad protectors are used between the sander pad and the abrasive disc, reducing wear of the backup pad's grip hooks. Our 9956RP pad protectors have 6 hole vacuum patterns as well as Abranet multi-hole patterns.
