also, it asks about stamp options on the ordering page? What does this mean and how do I know if I need one?
thanks,
Anne
Hey, Anne. Every balance has an option. This determines what the strength of the spring is. Each balance page has a chart that lists the options we have and what their strengths are. Compare these options to the stamps already existing on your balances or, even better, the weight of your window sash.
Hello! So if the number on the balance says 31 4 I am looking for option 3140 on the ordering page?
Thanks,
Anne
I agree. I think that's the best way to go. However, you might want to weigh your window sash just to make sure.
What do the markings "KM" or "LM" on the balance indicate?
Thanks,
Anne
It varies from balance to balance, but usually that kind of marking is a manufacturer tag.
