Identifying the replacement sash balance that I need
A handy person from New Hampshire says:

Here is what I can read from my old Andersen sash balance:
- Andersen Corp Bayport MN
- BB 425
- PAT No 3146488 1985
- Size 6 1/4" x 2 7/8" x 3/4"
The size of the window sash is 30.5" x 24.5"

I think the key stamp here might be "425." Is that printed differently than everything else, perhaps larger or off by itself? If so, see our 24-431 Andersen sash balance.
