ABSTRACT:
As a replacement for a permanently installed glass window of the sand blast cabinet of a product-finishing apparatus, which window, as might be surmised, is unavoidably scratched by sand or other abrasive particles during operation of the apparatus and thus ultimately becomes difficult to see through, the within invention contemplates use of a clear plastic strip, put up in a supply roll, and so arranged that successive length portions are unwound therefrom, when needed, to provide a window with optimum visibility through which the sanding or product-finishing operation is readily supervised.
