IDENTIFY NON-TILT WINDOW BALANCE

Hello,

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. 

Please note that your 32-3 stamp would normally indicate that you would need a 3230 spring strength option but a 26-pound sash would require a 3240 option to support between 23-28 pounds. 

I would also recommend double-checking the length of your metal channel since your stamp would normally indicate that the balance would measure 33" long, not including the end fittings. Take a look and let us know if you have any other questions or concerns.
