I recently bought 10 sheets of 80 grit sand paper belts for my belt sander. However the moment we turned the tool on it had an electrical fire. I no longer have a use for these sheets as no manufacturer makes a belt sander in this size. 21 3/4" x 4".The price is firm as this is what i paid for them and no one makes these anymore making them expensive. I prefer email as contact. please do not text the number.
