Need to replace this balancer. Window from house built in 1999.. Aluminum with mason army flange. Approx 52" x 55".

On side of balancer. U.??? E 24-D-40, then below 22-??-97

Notice the wedge at the end of the string. This attaches to the tilt brake.

I noticed the balance you are showing us was made by a company that is no longer in business. We think you should be ok going with our S770-25 balance with the 15-043 terminal clip that locks into the pivot shoe. The spring weight to go with this balance would be 25C for a sash weight of 17-22 pounds. We'd like for you to send an additional photo of the pivot shoe so we can confirm the 15-043 will fit into it.

I think I could use the existing terminal clip. Just cut it off the old balance string and use the new string. Do you think that will work?

Sure, but swapping out clips can be a bit of a hassle. You need to be very careful as those strings are under a lot of tension. You'll need a vice to hold the string in place, as well as safety gloves and safety goggles. Plus, in the end, it may not even be necessary. There's a chance the Series 770 will work fine with your shoe as-is.
