Spiral tilt window balance is blue tipped. Tube length is 29". The outer dried up plastic looking tube is all broken and OD is 9/16". The inner metal tube where the spring is spiraling onto is 3/8" OD. I just want to confirm the part I need is S600-29.

Thanks for posting. Correct! If the balance's outer tube is indeed 29" long and 9/16" (or 5/8") in diameter, and if it has a blue tip and is for a tilt window, then yes, the S600-29 is what you need.
