I have balance stamped 27F ra BSI looks like the one on the pictue series 795.
Approximate window weight should be 34-38 pounds. I don't see option F on you menue. Do you carry that replacement. Made about five years ago.
Thanks, Robert

The 27F stamp option would hold a window sash weight range of 30 through 34 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.
We would be happy to have the needed strength made for you, please allow 3 weeks for the initial order. We have added the needed stamp option 27F online.
