See either our S351-28 or S390-28. The only difference between these two balances is the depth of the bottom nylon shoe, or the heel-to-toe measurement, so compare both with your old hardware to see what matches best. You will need a stamp option of 2740. For a new Top Sash Guide, see if the 18-008 matches up. |
