Balancer 26 4 cx cmc 11

Hello, thank you for posting,

We can assist with replacements, but to further review, we will need to see clearer images of the top and bottom nylon attachments. We will also need to see the inside of the metal channel where we can view the connection point between the spring and pulley system. From there we can narrow down the series needed for your window. Thank you!

Thank you for the additional pictures,

With this combination of attachments, you could have either an S380 or S385 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. 

The length of the metal channel excluding the nylon attachments should measure 27" long and you will need a 2640 stamp option. Let us know if you have any additional questions!
