Hello there. The Series 600 is a Spiral Balance for tilt windows, and that does not seem to be what you have. The 17-012 Bracket is used with Non-Tilt Spiral Balances--namely, our Series 500. Double-check the length of the outer tube to determine the length needed. Let me know if you have further questions or concerns. |
