Old Balance from metal hung window

Thanks for contacting us, Carl. This balance was made by a company who is now out of business. That said, you may be able to substitute it with our S500-21. You would also need to use our 17-012 metal bracket. We don't have that nylon guide on the end of the spiral, but you should consider using our 67-002 nylon face guide. This is screwed on the face of the sash. You will also need our charging tool, so check out our 75-005 and the guide below to see how this works.
