Aluminum Window Parts - Unknown manufacturer

Question

I'm trying to replace these broken sash balancers.  The aluminum bars are 29" long and the only markings are a stamp at the bottom with the number 2830.

Hello,

Your photos resemble the S390-29 channel balance with 2830 strength options. Review the specifications to confirm it's a match. Thanks for posting!
