Channel balance replacement

Thanks for your photos. Based on what I see here, you have either our S380-28 or S385-28, depending on the depth of the bottom shoe. That's the only difference between them. I recommend measuring your shoe and referring to our dimensions to confirm the best match.

Regardless of which balance you go with, our 18-201 top sash guide appears to match your original quite well.
