Require the following window balances:
2 - 12" balances with 1110E
2 - 18" balances with 1710E
4 - 24" balances with 2320E
I measured only the metal portion of balances. The plastic parts at the end and front are the same for all balances and can be see in pictures I have attached.
If you require more pics please let me know.
