Thanks for writing in. Looks like you're replacing your spiral balance for a tilt window. Please confirm the diameter of the outer tube. If it's 5/8", you'll need a S600-29. If it's 3/8", you'll need a S900-29. In either case, you'll want to select the red tip option. Let us know if you have any questions. |
