Well, we have a couple options. If you wanted to go with the S600-48, you would need to drop down the top installation hole where the balance attaches to the jamb track by 1" to make up for the difference in size. Otherwise, we can custom make a 49" long balance for you. It shouldn't be an issue. Let me know how you want to proceed.
For your sash weight, I would recommend the Red Tip in either case. |
