I believe this is coming from a 1/2 34 window balancer on a Regency window probably installed around 1998. Just looking for two replacements

Hello,

It looks like you have either our S351-34 , with a 15-002 bottom attachment, or S390-34 , with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need.

It's hard to make out in your photo but if the stamp reads 33 3, then you'll also need a 3330 spring strength option for your replacement balances. Thank you!
