Window balance spring
Hey Todd. I am afraid I can't find an older order that matches what you're showing. Is there another email you may have used when placing it? Either way, I think we can narrow this down. This looks like a 15-199 Pivot Shoe, which works with both 1/2" wide Series 160 Coil Balance springs and 3/8" wide Series 165 springs. Can you tell me the width of your existing coil tape? Can you also tell me the exact weight of the window sash these balances support? We should be able to narrow it down from there.
That will suffice, thanks. Sounds like you have the 1/2" wide Series 160 springs. For the spring stamped #3.5, use the S160-03 3.5 pound spring. For the #5.5 stamped spring, use the S160-05 5.5 pound spring. For new coil housing, see the 15-150D. Let me know if you have questions.
Nope, this shouldn't matter. The spring weights will work no matter what order you stack them. Let us know if you have further questions.
