Window Track Parts

Hello there. See the 15-180 Pivot Shoe and 15-181 Balance Cover and 15-182 Drums. This system works with Series 190 Coil Balance springs. Let me know if you have further questions.

This particular assembly is sold as separate parts. The video below shows how to install a similar coil balance system--the general principles should apply. See the second video below that shows how to choose the correct spring weights for the Series 190 springs. Let me know if you have further questions.

Can you show me a clearer picture of the pivot shoe? So long as it's the 15-180, this is our best option, and to be honest I haven't seen a version that is less thick. Past customers have reported this shoe and the Series 190 work as replacements. 

Thanks for the kind words--we are here to help. I am afraid neither of these photos show the pivot shoe. They show the coil supports from the windows: the 15-181 double support and 15-186 single support, respectively. That said, both of these are clearly the supports that work with the 15-180 Pivot Shoe and Series 190 springs. In any event, it can be difficult to accurately measure the track itself. The only way to know for sure if by some chance this pivot shoe is incorrect is to remove your old one and compare the width and thickness to what we show below. If by some chance it was different that would give me some pause; but to be honest, based on everything you are showing me I have absolutely no reason to doubt the parts I've recommended should work for you. Let me know if you have further questions.

That would be pretty light of a window sash for this system. Could you verify that sash weight? We will proceed from there.

If the window weighs exactly 7 pounds or slightly more, than the S190-440 4 pound spring will work fine. One on each side of the sash equals 8 pounds of overall support--being within 1 pound of the exact sash weight is sufficient. Let us know if you have further questions.

Hey JD. Glad to hear the first replacement worked well! As far as these other windows that all weigh 22 pounds--don't worry about how many coils were in each window originally. The actual number of coil springs originally there actually doesn't matter. What matters is just getting the spring weights right. So for a window that weighs 22 pounds, go with the S190-540 5 pound springs and the S190-640 6 pound springs, one on each side of the the window. That would give you 11 pounds of support on both sides of the window, for that total of 22 pounds of support. Let me know if this makes sense. 

Again, the number of coils in the window doesn't really matter--just getting the weight support right does. I see what you mean though about the old coil cover being for a single spring--in that case though, you can just replace it with a 15-181 double support and 15-182 drums. Let me know if you have further questions.

Thank you very much for the kind words. That's exactly why we're here: to try and get you the parts you need so you can avoid a total window replacement. Do let us know if you have further questions or issues, and a very happy holiday to you and yours as well!
