I believe you'll need either the S351-28 or the S390-28 to replace your balances. To determine if which of these is the correct replacement, you'll need to measure the depth of your bottom shoe.
Our 2740 stamp will support a sash weighing between 19 to 26lbs.
Comparison of the S351 and S390 balance shoes.
