Hi: I need to replace a Nuair window balance that appears to be your part # S380-35. There are no stamping in the balance frame just the markings - 34 9 DX CMC 2. It is from a single hung non tilt Nuair window and the metal channel is 35" long and 9/16" wide. Please confirm the correct replacement part #. See images attached.

Thanks for posting. Can you please tell us the weight of your sash? This will help us determine the appropriate stamp option.

35" Series 380 with stamp option 3450 will carry a window sash weight range of 30 through and including 34 pounds.
This 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. |
