Window sash balance options

Thanks for posting! You are correct, the options for a channel balance correspond to the weight of the window. Are there any stamps or markings printed on the metal channel itself? If so, let me know what they are, and I can attempt to find you the best option. If there isn't, I will have to know the weight of your sash. You can determine this by removing the sash from the window and placing it on a scale. Any common bathroom scale should do.

Thank you. The 2350 option is for sashes up to 27 lbs. This should work for you. Let me know if you would like to try a stronger balance instead, we can custom make one for you.
