Just an additional note that balance attaches to the window frame via a clip that extends from the top of the balance that seats in a round hole in the frame channel.
I've included a pic of the top of the balance showing how it connects to the window frame.

Thanks for writing in. This looks like a S770-24 with our 15-170 clip attached as you noted, as well as a Rivet in top hole to use an S-clip like our 19-029 or 19-030 for installing to the window track. This balance has to be custom made due to its unique specifications, so I am sending you an email with a custom link to order (2) of them. Keep in mind the 15-169 is sold separately. Let me know if you have any questions before ordering. |
