Thanks for posting. The shoe resembles our 15-180. Just make sure the dimensions match. If this is what you need, it uses our Series 190 coil spring. Without knowing the sash weight I can't recommend a specific number, but you can match up the number printed on your existing coil springs to those under our Series 190 to find the correct part.

You can also see our 15-181 clip, 15-182 barrel, and 33-073 screw.

There was two other times they were able to help me identify a close balances them based on the size of the windows and the glass is there anyway you can at least estimate so I can order as I said this is very time sensitive and I need to order it today. Is there anything like I believe it was the series 120 or 130 where it's the balance shoe the coils in the cover all as a package

You have not given us the size of the windows or glass, but if you do we could try to estimate something. It is much easier to match up the numbers on the coils you have now, though. They should be located near where they screw into the shoe. You could also get the weight of the sash by placing it on a scale. Those last two methods are much more accurate than basing a spring weight based on window size.

They were given the first time I believe
10 windows total
35x34 (2)

36x58 (8)
can I just go ahead and use I think it was series 120 were all the parts are includedspend $40 a window rather than spending $120 a window I suggested to begin with

Thank you. For a 35" x 34" window, I would recommend our S190-640 for each side. For a 36" x 58" window, I would use an S190-540 and S190-640 on each side. Please keep in mind that these are educated guesses. I cannot guarantee that these parts will work on your window.
