28", please.
Top sash guide measurements:
-width- 5/8"
-height- 1 15/16"
-depth of top section- 5/8" (not including overhang of top flat portion)
-depth of bottom section- 3/8"
-screw hole (from top) 3/4"
-ledge that catches channel balance at bottom of top section (from top)- 1"
Would 18-065 work for us, even though the ledge to catch the channel balance is at the top, instead of 1" down from the top?
Thanks!
