Hey there. Check out our S380-30 channel balance. This come assembled with the 19-005 channel balance top and 15-005 bottom balance shoe. You will need to compare your balance with ours to see if this will work. If everything looks good, then you can go with the 2960 option that holds a sash weight of 32-35 pounds. |
