SWISCO - The Replacement Hardware Authority

9#27 sash balance

A handy person from South Dakota says:
My balancers have the following stamped on them

E41 9#27 7-77

My best guess is 1033.

What do you say?

Actually, I recommend our 24-939. This can replace Andersen balance boxes stamped with 9#27.
