s380 balance question

It appears to me by looking at your examples that I need a 30" series 380 w/option 2940 (#stamped on my balance). The problem is the shoe. The 1/2" demension is fine but the other one is not an inch it is 7/8". Will this be a problem?

I'm sorry, I'm not sure which dimension in particular it is you're referring to. Do you mean the heel-to-toe meaurement? If so, then it's common that these shoes wear down a little over time.

Yes,from heel to toe. In the picture, the 15-005 shoe shows a one inch demension heel to to and mine is 7/8". And by the way, what does the 2940 stamped on my balance mean?

Thanks for confirming! Like I mentioned, it's possible the shoe wore down. Even if that's not the case, the 15-005 is actually the smallest option we have. If you absolutely need it to be 7/8", you can always shave it down a little.
A stamp of 2940 indicates how strong the spring is. Two balances with the 2940 stamp can carry a window sash weight of 23 through 28 pounds. |

Thanks, I'll try a couple and see how that goes before doing some other windows.
