Jeld-Wen ( oct 2002) window balance spring

Hello,

With this combination of attachments, you could have either the S380-26 or S385-26 channel balance. You’ll need to measure as shown below. The Series 380 has a 1" bottom attachment, and the Series 385 has a 1-3/32" attachment. 

You'll also need 2560 spring strength options for your replacement balances, which will support a sash between 28-30 lbs. Thank you and let us know if you have any other questions or concerns.

Great! We'll be here if you need anything else.
