Hi, I have old wooden windows. The channel balance is 37" metal part. On both ends are the attached pictures.
I need replacement for those as well as any sealing parts that can be worn out. The house was built in 1980. Many windows function well but if we were able to buy parts and replace we will place a large order for all windows.
Please let me know if there are any questions for me to answer.
