I believe I need to order the shoe as well. I want to make sure I am ordering the right thing. The coils have a 9 stamped.

Need both sides of the window.

Can you show us the pivot shoe these coil balances attach to? The identity of the coil balances determine the identity of the coil springs. Finally, it's actually hard to say if this is either a 9 or a 6! This is unfortunately a common problem with coil balances. I highly advise weighing the window sash. Give me that exact weight, and I can tell you the spring weights you'll need.

Thanks! Your old shoe looks like our 15-177, which is designed to be used with the Series 152 spring. Look these parts over and see if you agree with my assessment.
