Stamp Option for my S380-35

Question

I am unsure of the stamp option to chose for my 4 channel balances that have to be replaced. The best fit seems to be 35" Series 380 Channel Balance Product Code: S380-35. The stamp on the original says 34-5 GA2 CMC 19

Thanks for posting. I recommend the 3450 option, based on your stamp. This can support a window sash weight range of 30 through 34 pounds. Does your sash's weight fall within that range?

Please keep in mind that the weight range information is based on 2 balances per sash. Balances are designed assuming friction in the jamb weather-strip will carry a portion of the sash weight. Suggested sash weights are approximate.
