My windows are Capital 9555 series vinyl double hung windows with a measure in 31"x31" as shown in the attached files. The coil width is 0.5".
Need your help to determine the type of the coil.

Thanks!

Your pivot shoe looks like our 15-180, which is commonly used with the Series 190 coil spring. See what you think.

Thanks for the help! I thought it'd be S190 coil spring as well, though not entirely sure which type of S190 coil I should pick from the selections of 440,540,640,740,840. The number code on my coil is 7 as you can see in the 2nd image. Does that indicate I should choose S190-740?

Thanks again!

Yes, if the number on your old spring reads "7" then our S190-740 would be the best option. Each of these springs is rated to hold 7 pounds, so if you have two springs altogether then they are meant to hold a 14 pound sash. If you have four springs altogether, they're meant to hold a 28 pound sash, and so on. You can always weigh your sash on a scale to confirm that these are correct.
