34-9 BA CMC 4 Channel balance for a NuAir Window

Question

I'm looking for replacement channel balances for a NuAir window. The part is 35" long, not including the plastic parts, and is 1/2" wide. The marking on the part is 34-9 BA CMC 4.

Thanks for contacting us! I believe you have our S385-35 channel balance. Your stamp uses an older rating system that we don't have, but one of our more modern stamp options should still work fine. You will need to weigh your sash on a scale and refer to the S385-35 store page to confirm the best option.
