Thanks for posting. This balance appears similar to our S377-30. Check it out and let me know if you agree.
As for the balances marked 2930 and 2940, are they in two different windows? If so, you should stick with those same numbers. It's pretty important you get the exact stamp option you need. If it's too strong or too weak, the windows won't work well. There is a list of stamp options under the S377-30 that also details how much sash weight each option can hold up. You should weigh each sash whose balances are being replaced to ensure you are getting the right option. |
