Thanks for posting! We can help you determine what stamp option you need, we just need a bit of information.
First, what is the length of your metal channel? Please do not include the plastic attachments in your measurement. Second, what is the Series of your balance, as determined on our own site? Finally, we will need to know the weight of your sash. You can remove it and place it on any common bathroom scale to determine this. |

Choose stamp option 1620, this will carry a window sash weight range of 8 through and including 12 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. |
