26E Tilt window balance
Thanks for writing in. Hm, I'm actually not certain, as this balance looks a little unusual. Does the hook install into the window at the top of the frame, or does it connect to a pivot shoe at the bottom? This will determine what to do next. Just let us know.
Thank you! In that case, this will have to be a custom order. Specifically, I believe you have an S770-26, but with the bottom swapped out for our 62-105 hook. That's what would make it custom in this case. We would also use the 26E stamp, which carries a sash weight of 26 through 30 pounds
Does that look good to you? If so, let me know how many you need and we can email you an order link and price quote for the requested quantity.
