Replacement Part Tensioner

Hello,

We'd be happy to look into this for you but we'll need a bit more information to narrow down your options. To get started, we'll need to see the end fittings of your balance uninstalled, as well as 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. With this combination of attachments, you could have either the S380-27 or S385-27 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 2640 spring strength options for your replacement balances. Thank you and let us know if you have any other questions or concerns.

Comparison of the S378, S380 and S385 balance shoes.

You'll see a list of options on the S385-27 product page. You'll need to choose 2640 for your balances based on your 26 4 stamp code, which will support a sash between 19-26 lbs.

It's our pleasure. Just let us know if you need anything else.
