I am looking to replace bouncers for tilting windows. The solid rod is 29 inches long. Please let me know what part number I need to order to replace these.

thanks,

Tufan

Hello,

Your photos resemble the (3/8") S900-29 or (5/8") S600-29 spiral balances, depending on the diameter of the plastic housing tube. You'll also need to weigh your sash to determine which option you'll need. There is a chart on the product page that explains how to choose your color option based on the sash weight. Thanks for posting!
