Unfortunately the company that made your balance system has gone out of business. That said, I believe that our S500-18 spiral balance can work as a substitute. You would also need a balance bracket like our 17-012 to attach it to the sash. The brackets hooks onto the end of the balance spiral.
Installing can be a bit tricky, but we can help. 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. |
