Hello, Stephen. I don't think you will be able to find this part anywhere. I believe these were sold in some hardware stores as another way in holding the sash in place when either the rope or chain broken on the window pulley system, but not for a long, long time. Maybe check with an older hardware store in your area to see if they have any in their old stock. We also have the 20-001 sash spring. I can't confirm if it will work, but it may be worth looking at given the circumstances. You would install this on the top of the bottom sash. It creates friction between the sash and track to help hold it up. |

That's just how it goes sometimes, Stephen. Finding parts like this can be like treasure hunting. I've definitely crossed state lines in the effort. I'm sorry we couldn't offer a better solution for these older windows. I wish you luck for this project. |
