Window Spiral Balance Top Needed

Hello, Richard. This top isn't available by itself. I'm afraid that you'll need an all new balance.

If you need help identifying what balance you need, please tell me whether this is a tilt or non-tilt window. Please also tell me the diameter of the outer tube. Note that the outer tube appears to be missing from the balance you're showing here, so you'll need to measure a balance that still has it.

Perfect, thank you! Based on that information, I recommend our S900-25 spiral balance. I think this will work well as a replacement.
