Paul,
Thank you very much for your prompt response. Regarding your question, the length of the tube (and I've measured it as indicated in your website) is 33 inches. I have other windows (shorter) and there the balance tube is about 23 inches (I've not disassembled those yet waiting to see if these spiral balances are in stock).
Thanks again for your help.

Thank you, Paul. Yes, probably that is what happened and that is why it looks weird in the picture.
Thanks again for all your help. I really like SWISCO and the attention that the staff provide to the customers.
