Abstract: A device adapted to be attached to a power sander for confining and removing dust and debris during operation of the sander. The device comprises a cover that fits over and conforms to the sander shape with surrounding wall members whose lower edge is in the same plane as the sander's movable platen. An outlet opening at one end of the device is connectable to an air vacuum machine and interior walls form elongated air passages along opposite sides of the movable sander platen to facilitate efficient air flow and dust removal.
