Before I purchase replacement channel balances , please check to see if I've identified the correct part. I think I need
S390-24, 2330 weight.
The top piece on the channel balance has guide flanges, but I didn't find a corresponding part. One of my windows has a top piece without flanges and it seems to work so I think
19-005 top should work.
The balance shoe measures 1 1/8" along the bottom, so I think it is part
15-001.
The metal channel is 24" long. Windows do Not tilt.
Thanks.
