Question

I need to order S380-37 Channel Balances. The stamp on the old balance says 3635, what stamp option should I order?

Thanks,

Tom

Thanks for writing in, Tom. That is an interesting spring weight stamp number. It falls between (3630) for a sash weight 18-23 lbs. and (3640) for a sash weight 23-30 lbs. The best way to decide which stamped option to choose, you will need to weigh the sash.
