I need to replace these springs in several of my windows. The windows are 20 years old.

Your window balances can be replaced with the S378-27, S380-27, or the S385-27. To confirm which of these is the correct fit, you'll need to measure the depth of your bottom shoe.

I believe you'll need the 2630 stamp option. It will support a sash weighing between 13 to 19lbs.

Comparison of the S378, S380 and S385 balance shoes.
