Alcoa Window will not stay open

Thanks for posting. It sounds like you have a problem with your window balances. I'd be happy to tell you what you need to replace them, but I'll first need to know what balances you have installed in the window.

If you can, please remove the balances from the window and take a few pictures of them separately, then upload them here for us to see. Alternatively, you can look through our Support Balance Hardware Section in order to find the correct balance for your window.

I think those pictures are just what we needed to see! Looks like you have tilt window spiral balances. Take a look at that page and see if it looks about right.

You're in luck here. If your windows are dropping and you have spiral balances as your support system, you may be able to simply re-charge the spiral instead of replacing the whole balance. Take a look at the video below, which shows the proper way to replace these balances. It also shows how to charge the spiral. You can use a tool like our 75-006.

See if this does the trick for you. If you're charging the spiral but feel no tension, then it's likely that it's shot. In that case, you would need to replace the balances. One step at a time, though! Let's see if charging them works for now. If it doesn't look good, let me know and we can work from there.

Great! That image is a huge help. Take a look at our 15-173 and see how it matches up to your hardware.
