Window balance with a 2730 stamp on it

Question

I have 2 windows where the balance on one side is hanging down/disconnected from the hook/spring mechanism.  I presume it is smart to replace both sides (like headlights) and I have successfully removed the windows to get pictures of the part I am looking for. Hard to show them installed as they dont really work very well.  Clips at the top, in the window frame, for holding the balances, are not real robust.

Thanks for your post! Your window balances can be replaced with either the S351-28 or the S390-28. You'll need to confirm the depth of your shoe to determine which series you'll need for the replacement.

You can select the 2730 stamp option, which will support a sash weighing 13 to 19lbs.
