what size belt do you need?? most standard sizes are available at the Depot. I had to go to sear$ to get a 4x21 for an old craftsman that I have. if necessary, take the sander with you to the store to check if any of the stocked belts will fit. to determinm the size, use a dressmakers tape measure to check the distance around the rollers and the width of the platten. you can order belts from the web at:
