Broken pivot shoe
The only way to identify any window component is to use the original as a reference to ID its size, design, and compatibility. To start, I'm going to need you to remove an undamaged version from the frame and show me a photo of it without obstruction. I'll also need you to measure the width and thickness and then write out what you get right here in this thread. Thanks!
They are approximately 1 1/4" wide x 1/2" thick.
Let me know if these pictures are enough to identify. Thanks!
Thanks! These photos are still very helpful, as are your dimensions. Being 1-1/4" wide x 1/2" thick, my top recommendation is the 15-046. I actually think this might be the modern equivalent of your original. Despite the differences in style, it's the same size and is compatible with the same kind of spiral balance. I think this is well worth considering, but look it over and see what you think.
Awesome, thanks so much! We really appreciate it. Please let me know if you had any follow up questions. We're always here to help.
