Need spiral balances

Thanks for posting! Before I can offer applicable replacements for these balances, I just need to know a bit more information.

First, are these windows tilt or non-tilt?

Next, what is the diameter and length of their tubes? Please give separate measurements for the top and bottom.

Finally, I will need to know the weight of the sashes. You can determine this by removing them from the window and placing them on a scale.

Thank you for your cooperation. Let me know what you come up with!

Thanks, Joe! I just need one last piece of information: are your windows tilt, or non-tilt? Knowing that, I can recommend a balance for you.

Thanks, Joe! I'd recommend the S600-34 spiral balance, then. I'd also recommend the Red Tip, as it can support a window sash weight range of 12 through 30 pounds. These balances are non-handed.

As for the "terminal receptors," it sounds like you're describing what is known as a Pivot Lock Shoe. I do not know what you may have without first seeing a picture of it removed from the jamb, so as to identify its style. That said, please browse through our Pivot Lock Shoe Section and see if you can find something that works.
