Hello, thanks for offering this service. I am replacing a broken part and need help identifying the correct replacement.
The channel width is 9/16" so I know that is the 1/2" model. The length is 33", metal channel only, plus the two ends. It is hard from me to determine which part number I need. As listed in the subject line the channel is stamped 3250. Perpendicular to the end of the 3250 stamp is a stamp B.S.I. and adjacent to that there is a stamp 0A or OA.
I can upload additional pictures but your system limited me to five. Let me know if they are needed.
These are originally from Windowmaster windows purchased in 2003.

Hello,
With this combination of attachments, you could have either an S380-33 or S385-33 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 3250 spring strength options for your replacement balances.
Thank you and let us know if you have any other questions or concerns.

Thank you for the reply. I am measuring the part as you mentioned. Based on these pictures I feel it is over one inch so is it safe to assume it is the 15-004 1 3/32"?

As long as it measures over 1", the S385 would be the way to go. These attachments can wear down a bit over time, so don't be too concerned if you're not coming up with exactly 1-3/32".
