I need some help selecting some replacement 1/2" Channel Window Balances (Non-Tilting). I can't find any manufacturer information on the actual window sash but the manufacturer of the original channel balances is Caldwell. Included are a bunch of photos (I'd rather provide more information than less).
The actual plastic hardware on each end of both balances is IDENTICAL however, the lengths of the metal sections are 20" and 29". The shorter 20" metal bar has markings of what I think are 19 9 30 FD Caldwell HOWEVER, I just pulled the other Channel balance from the other side and it reads 18 4 JS.
The longer 29" bar reads 28 4 JL Caldwell.
I believe the top piece is part # 19-002
but I'm having difficulty identifying the bottom piece. I believe it is either #15-001
, or #15-003
but my piece appears to be more triangular than either of the first two.
Thank you in advance for all of your help in identifying this hardware!
