Hi there. Yes, this is called a spiral balance, which regulates the opening and closing of the window. The videos on this page show how to remove and replace these balances, as well as how to identify the right replacement. Broadly speaking, for a tilt window you will need either a 3/8" Series 900 or 5/8" Series 600. Let us know if you have any further questions. |

If the outer tube is 34" long, and 5/8" in diameter, then you need the S600-34. If the sash weighs 25.6 pounds, choose the Red Tip option. It supports a sash in the weight range of 12 through 30 pounds. |
