My channel balance has 27TGX stamped on it but is 28" long. Not sure which option to order (28d, 28c or 28b)? It is from a double pane double hung window 42" wide by 60" tall (sliding part of window is 42" wide by 29" tall).

Please remove the window sash and place it on a scale.
We need the weight of the window sash in pounds to determine the proper stamp option.
The window sash is 25 lbs.
S770-28 balance with stamp option 28D will carry a window sash weight range of 23 through 28 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.
S770-28 with stamp option 28B will carry a window sash weight range of 12 through 18 pounds;
S770-28 with stamp option 28C will carry a window sash weight range of 18 through 23 pounds.

What are the sash weight ranges for the 28B and 28C options? I have other windows that will need new balances in the near future.
