Issue with replacement

A handy person from Houston, TX says:
Hello, I actually can identify this part by myself. The issue is that the aluminum windows that came with my house don't appear to have the bracket mentioned in all the videos. I am really just looking for some advice on how to install these replacements on this type of window which is nearly ubiquitous around here.

Thanks for posting! I can tell based on this picture that you have either the Series 400 or Series 500 spiral balance, depending on the diameter of the tube. I'm not sure about the bracket, though. Could I see a close up picture of the window sash?

Sorry for the delay but I was out of town for a bit. I checked some of the other windows and could not find the bracket. Here are the photos I took

Not a problem! Now, based on these new pictures, I believe you have a builder's grade window. Unfortunately, this means that the sashes are not designed to be removed.

I believe that the balance you need is our Series 400 3/8" diameter non tilt spiral balances. Just confirm the diameter, just in case! The length is also determined based on the length of the tube. The bracket is like our 17-010, located inside the bottom part of the sash.

To adjust or remove the broken balance, first raise the sash and have someone hold it up for you. With the sash up, hook the balance with our 75-004 tool, unhook it from the sash clip, and unwind it. Be careful if the balance is charged, as it could spin out on you.

After you unhook balance and discharge it, lower the sash and unscrew the balance at the top, then raise the sash one more time so that you can pull the balance out from the bottom.

To install a new balance, drop it down from the top of the sash and screw it to the track. Then raise the sash and use the charging tool to give the balance three or four clockwise turns.
