Hello,

These non-tilt spiral balances are no longer made with the mounting bracket attached to the spiral but we now recommend the S400-27 balance with the 17-031 bracket. You'll also need to weigh your sash to choose the corresponding color tip option. Thanks for posting! 

Color Tip     Sash Weight Range

Red              10 to 22 lbs

Green          14 to 26 lbs
