Window Balancer Kinro

Hello,

With this combination of attachments, you could have either an 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.

Your pulley is broken, which is why it looks different. The end attachments and metal pulley clip are what we look at when recommending replacement balances.
