Replacement Spiral Balances for Alcoa Tilt Window

Question

Hello, I need to order two replacement Spiral Balances for an Alcoa tilt window. The tip is colored blue and the outer tube measures 29". There are no visible manufacturer markings on the one I removed from the window. Please advise me on which part I need to order. Thank you very much,

Thanks for posting, Jeff. Can you confirm the diameter of the outer tube? If it's 3/8", I recommend our Series 900 spiral balance. If it's 5/8", I recommend our Series 600 instead.
