Stamped DISCO 2189, PGT PART # 7683Z. Pls see pictures. Looks like your 81-153 except adjustment screw is above attachment screw. Any chance you have these in SS? Thanks, Mike

Our 81-153 roller was used by PGT. It's possible that yours is a slightly different or older version of our part. Concerning the placement of the screws, you can use the upper hole in the door stile (which was for the adjustment screw) for the mounting hole and the lower hole for the adjustment screw. You might need to widen the hole a little for adjustment screw, but I have done this in the past when faced with the same situation. Unfortunately, we do not have carry it in the stainless steel. .
