Thanks for posting! I'm not quite sure what stamp would be best. 20S doesn't correspond to any stamp options that we have.
Could you tell me the weight of your sash? Once I know that, I can offer the best possible option for you to choose!
Paul:
I have two windows that need new balances.
They both have the same length and ends.
The one stampe 20S 28 weighs 22.4 pounds
The other is stamped 2040P and weighs 25.1 pounds.
I hope you can identify replacements.
Pete
I guess I could move the springs from the old balances to the new ones if that would help.
Paul'
I am confused.
My unit is stamped 2040P not 2050.
Where do I enter the sash weight?
