I have older double pane windows, non tilt sashes. No problem identifying the channel balances. The problem I have is removing and bigger problem of installing the sash.
The left side of the sash is inside aluminum channel and the window has part that fits into the channel. Once the right side is released, the sash can be moved/swung to the left - kind of hinge mechanism, and then pulled out. But can't be put back without removing some stuff. I will need 10 to 14 balances plus additional parts, but if I cant put the sash back it would be wasted money. Do you know of any instructions for this type of window?
The balance has marking BSI 2830. It is 29 inches long. Will have to get several complete balances. On several balances I need the top and bottom plastic pieces. I also need bunch of the retaining clips that are screwed inside the aluminum channel which also houses the balance. I enclosed several pictures.
The windows are made out of aluminum. Made by G&S Metal Products, Inc. Never heard of them. The right balance might not be hard to replace but the left one will be very difficult. Once the sash is moved up to the retaining clips, it can be pulled from the right side and it swings on a hinge to the left. See the picture. So far I found it impossible to put it back with the left balance.
