Window Channel Balance Indentification

Question

I am trying to figure out exactly which channel balance I need to replace this one that no longer works. The stamp is 3230 and then has BSI and OJ on the stamp.

Hello, thank you for posting,

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 33" long and you will need a 3230 stamp option. Please review and let us know if you have any additional questions.
