need spiral balance for MW windows

Hello. I just spoke with someone at Plygem Windows in Rocky Mount, VA (closest location to my home) and they referred me to you. I have three MW windows in my living room and two of the windows won't stay up when I open them. Upon closer inspection, the two windows in question have one broken spiral balance apiece.

I am hoping you can help me figure out exactly which replacement parts I need to order. On the phone, the woman ay Plygem told me I needed "spiral balances for twin seal vinyl siding single hung windows." I am attaching several photos in hopes that this provides you with more detail, and am more than happy to take additional pictures if necessary.

thank you!

okay, more pics are attached. i measured the length of the white tube and it comes out to 29 inches. not sure what color the balance tip is...in one photo (taken of the end of the 29'' white tube) it appears there is a white or clear colored encasing inside, but im not sure if that is what you are referring to.

again, if i need to take more pictures, i am happy to do so. i want to make sure i get this right!

sorry it's taken me this long to reply, but it's been so hot here that our windows have been closed and the AC has been on literally every day since, so our "window issues" haven't posed much of a problem the last few months.

the diameter of the plastic tube is 3/8 of an inch and i've attached photos of both ends of what the spiral portion of the balance hooks into, in hopes that one of the photos shows the pivot shoe.

please let me know if i can provide any additional information. i am hopeful that we can get our windows fixed before it becomes "open window weather."

thank you.

sorry to sound so un-handy, but which part of the window is the "window sash" and how do i remove it?

I did my best to weigh the window sash, but it does not come out of the frame easily, so I leaned it back (as if I was going to clean it) onto a bathroom scale which I held level (see pic for details).

For what it's worth, the scale read 20 pounds both times I weighed it.

In all honesty, it probably weighs a little more than that because part of the sash was still locked into the window frame. I was worried that if I removed the sash completely, I would not be able to get it back in.

If this helps, the bottom part of the window sash that connects to a metal bar in the window frame is surrounded by a blue casing. And not far from the blue casing is the serial number "590CSB."

Thanks for your continued help.
