Your window balances can be replaced with either the S351-16 or the S390-16. To determine which of these is he correct fit, you'll need to confirm the depth of your shoe.

Comparison of the S351 and S390 balance shoes.

To determine the correct stamp option, you'll need to look for a stamp/marking on the channel. If there isn't one, you'll need to confirm the exact weight of the window sash.

There is a chart below the product description that lists the weight ranges each stamp will support.
