Tilt window balance

Thanks for posting. This looks like it might be a Series 770 Channel Balance, but that S-Clip connected to the rivet on the top of the metal channel gives me some pause. Is it necessary? Is that how the balances connects to the window track? Let us know. Also please let us know the length of the metal channel. Many thanks.

Thanks for getting back to me. I am forwarding this discussion to one of my senior colleagues who specializes in these balances. We'll get back to you as soon as we can with more information. Many thanks.

Thank you for getting back to us. You are going to need a custom made 26" Series 770 with a stamp option of 26C, which is for a window sash in the weight range of 17 through 22 lbs. We will install a rivet in the top of the balance to accept either the 19-029 or 19-030 S-Clip. To know which S-Clip you need, we need to see an undamaged balance. How many balances do you require? From there, and with a picture of an undamaged balance, we can get this started for you.
