Spiral spring connection hardware

Hello,

This spiral balance with a fixed mounting bracket is no longer available, but you should be able to use the (3/8) S400 with the 17-031 backet or (5/8") S500 spiral balance with the 17-012 bracket, depending on the diameter of your housing tube. There is a chart on the product page that explains how to choose your color tip option based on the sash weight. You'll also need to measure the length of the balance tube, not including the spiral, to confirm the correct replacement. Thanks for posting!
