Balance Coil Replacements Needed

A quick learner from Ypsilanti, MI says:
I have attached pictures of what coils need replacing in each window. The windows are are vinyl, single sash,double pane windows. Two of them are 22w x 29h and two are 33w x 29h. The Series 140 look like they will do the job for both windows, assuming I get the double coil for the larger window? Do I order left and right coils?

Thanks for your help

Note, in the post with pictures, that the double coils for the 33w x 29h window sash are located at top of window so I assume the coil spring needs to be long enough to reach the lower sash.

The 22w x 29h sash weighs 12 lbs.

The 33w x 29h sash weighs 19 lbs.

The Series 140 would be an easy solution, but I'm not sure if they'll work in your windows. Can you show me a picture of the pivot bar that inserts into the shoe? That will help me determine if it can work with the Series 140 balance.

In addition to the previous post picture, note that the pivot bar is rectangular in shape: .2 inches high and .3 inches wide.

Thank you! Yes, I believe that pivot bar will work with out Series 140 coil balance. For the 12 pound sash, I recommend our S140-7, and for the 19 pound sash I recommend our S140-10. Please just make sure you have enough room in the jamb track to fit these balance systems!

The larger window 33w x 29h, had the coils mounted at the top for some reason(see picture). This required a coil that is about 54 inches long. Will the S140-10 coils be long enough to work from there, or can I just mount them lower and still have full window operation?

Paul from SWISCO responded:
The travel is about 35", so I would mount the Series 140 near the middle of the window.
A quick learner from Ypsilanti says:
I just wanted to thank Paul for his assistance in determining the correct balance coils for my windows. I installed them without too much trouble today and the windows are operating much better. Your friendly and timely assistance means I will always turn to SWISCO first for any future hardware needs.
