Balance, new spring?

Hello,

Thanks for writing in! Your window balances can possibly be replaced with the S380-27 or the S385-27. To determine which of these is the correct replacement, you'll need to confirm the depth of your bottom shoe.

I believe the 2660 stamp should work for your repair. A pair of these will support a sash weighing 30 to 33lbs.

Comparison of the S378, S380 and S385 balance shoes.
