This looks like either an S351-29 or S390-29, depending on the depth of the bottom nylon shoe. Compare both with your old hardware to see what matches best. You will need a stamp option of 2830. For the Top Sash Guide, is there an undamaged version on any window you can remove and show us from the front and side? That will help narrow things down. Many thanks. |
