Spiral Balance ID

Would you please identify the replacement parts for the spiral balance in the pictures? The balance is covered with a thin plastic tube which measures 9/16" diameter. The length is 25" measured between the pipe ends in the pictures ignoring the hook.

Thank you.

Hi Masashi. Confirm the diameter of that outer tube is 5/8", and the length is indeed 25". If so, see our S600-25. You will need a Blue Tip option. Let me know if you have any other questions.

The outer plastic covering is thin and somewhat soft, so I cannot distinguish between 9/16 and 5/8. I would think the thinner estimate would be a safer choice.
Thanks,

Hi Masashi. I understand; it is indeed tricky to measure these balances were the outer tubing has become flimsy. However, for these tilt window spiral balances, the only other option is 3/8". Therefore, I think the S600-25 is probably the better choice. Let me know what you think.
