Good afternoon! Thank you for posting. Before I can offer an applicable stamp option for you, I would first need to know the weight of your window sash. You can determine this by removing it from your window and placing it on a scale. Let me know!

Thank you. I would recommend the 19R stamp option, which can support a window sash weight range of 10 through 17 pounds. I think this will still work for your 9.8 pound sash.
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. |
