hi, I'm looking for this sash balance as the previous one's spring has failed.

serial number on balance 31Bu.s.b.

length of metal 32
total length 33?
Channel depth 5/8?
Channel width slightly under 5/8?

Let me know if you need additional info.

Thanks,
Yi

Hey Yi. This looks like an S390-32 Channel Balance. For a stamp option, choose 3120. Let us know if you have further questions.
