Thank you for posting! Before we work on your balance stamp, can you first confirm the length of your metal channel? A stamp of 24HD usually indicates a metal channel length of 25". Please let me know, and remember--don't count the plastic shoe in your measurements. Just the metal channel.
Once we have your appropriate balance length, we can determine the best stamp option for you to use. |

Thank you. Now, there actually is a 24HD stamp for the S750-25. It can carry a window sash weight range of 18 through 22 pounds. Does your sash's weight fall within that range?
Please keep in mind that the weight range 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. |
