A hand sanding block accepts the continuous sanding belts that are normally used on electrically powered belt sanders. Shoulder stops and biasing springs within the device allow for two positions of the block and keep the movable tensioning arm from coming apart from the block. One position, the withdrawn position, allows for easy removal, replacement, or adjustment of the continuous sanding belt. A second, or extended position, tensions the sanding belt to keep it in place on the sanding block.
