Hello,
I just installed the
S390-30 : 30"
Series 390 Channel Balances that is just purchased from you. The series is stamped 2930 on the balance channel. While installing, the balance twisted out is the window when I went down. I looked at the sash and saw the guide had been broken for a long time. When researching for a replacement, I was unable to identify which one I need. I'm sure you will be able to figure it out right away lol. The windows were made by Atmos Corporation which I am pretty sure is now defunct. I appreciate the help.
Best Regards,
Eric
