Window 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. If you could show us the connecting point between the spring and pulley inside the metal channel, as well as both end fittings, 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 and a 1" deep shoe, you'll need the S380-27. Note that we also offer the Series 385 has a 1-3/32" attachment. 

You'll need 2630 spring strength options for your replacement balances. Thank you and let us know if you have any other questions or concerns.
