I need several sets of the sash window channel balances. The metal frame is 25.5"
I have no idea how to replace the plastic parts. I'd rather just replace the whole balance. However, the hook comes off the very bottom, not in the middle of the plastic bottom part. From the top of the metal to the top of the hook (where the hook is attached to the plastic) is 26-1/8"
The number on the balance is 25DS36 Then sideways is g.R.I. then there is RE in smaller letters.
Do you have something complete that I can order.
