We have Norandex windows and need window balances. Number stamped on balance is 3635 BS1. We looked at the part S380-37 but do not know the option for the sash weight range. Can you recommend which one please? Thank you.

The window balance is 37". What other measurement do you need?

Your stamp is a little unusual. Can tell me the weight of your sash?
