Can you show me a picture of the balances currently in the window? I'd specifically like to see pictures of its top and bottom, as well as any stamp printed on it.

I believe you have wood sashes with an aluminum jamb liner, which has a press spring on the back of the liner. There are two options you can consider.
First, you can remove the sashes and one jamb liner and take them to any mill work and they can find a replacement jamb liner for you. This might be the ideal option, since you can get something specifically for your window. Secondly, you can consider our 5/8" diameter non tilt window Series 500 spiral balance. This is commonly used on wood windows throughout the decades. Based on your dimensions, I think you could use our S500-26 for the top sash and S500-27 for the lower sash, along with a 17-012 balance bracket to attach it to the bottom of the sash. Being an old window, the sash might not be removable. However, we do have a possible solution. With someone helping you, you will need to drop the new balance in from the top of the sash, screw it in at the top, then let the spiral drop down. You will then raise the sash and, while someone holds the sash in the open position, spin the spiral up to the bottom of the sash. Finally, with our 75-004 tool, give the balance about three turns to charge it and lock it to the end into the sash clip. Let me know if you have any more questions. |
