Thanks for posting, David. Looks like you need a balance, not a sash. The sash is the glass panel itself, while a balance is a spring on either side that holds the sash up.
That said, I cannot identify what you have on this stamp alone. I will need a few more pictures. Please show me both ends of the metal channel and whatever is attached at the end of the cord, be it a metal clip or a nylon shoe. Please also tell me the length of the metal channel and the weight of your sash. Thanks! |

This looks like our Series 770 balance. For a 29" length, go to S770-29 and choose 29C option, this will carry a window sash weight range of 18 through 23 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. |
