Tilt in sash balance

Thanks for your post! This balance can be replaced with the S770-28 with a 28B stamp. Although, your existing assembly installs using a clip, the replacements will need to be custom assemblies, so that we can add the rivet to them.

In the event you need to replace the balance shoe, I believe you'll need the 15-129. Be sure to double check the dimensions on the website to confirm.
