Hello there. See if the 18-166 matches your Top Sash Guide. For the channel balance, see either our S380-30 or S385-30. The only difference between these two balances is the depth of the bottom nylon shoe, so compare both with your old hardware to see what matches best. In either case, let me know if you have questions about what stamp option to choose. |
