Window balance

Question

I am searching for replacement window balancers. I am having a hard time determining the correct ends. The metal is 31" long x 1/2" . Stamped on it 30 3 D H. The wings measure 15/16 apart 1"deep. Any help would be greatly appreciated. Thank you

Hello,

With this combination of attachments, you could have either an S380-31 or S385-31 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 3030 spring strength options for your replacement balances.

Thank you and let us know if you have any other questions or concerns.
