Hi, I want to replace two window balances for a non-tilting vinyl, two-pane window.  The balance is 26" long, stamped 25-4 IT CMC 9.  the window weighs 21.8 pounds.

Hello,

We'd be happy to look into this for you but we'll need a bit more information to narrow down your options. If you could show us the connecting point between the spring and pulley inside the metal channel, that would help us confirm if our stock balances could work for your repair or if they would need to be special ordered. Thank you!

Thanks for getting back to us! Based on your photos, 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 2540 spring strength options for your replacement balances. Thank you and let us know if you have any other questions or concerns.

Thanks. Looks like it's closer to 1-3/32"

In that case, see the S385-26 channel balances with 2540 strength options.
