Balance for Marvin Coast Line windows

Question

I have windows that are made by Marvin
Coast line series. The balances are broken
The balance looks like plastic tube 3/4" in diameter attached with the screw tithe window frame on the top and on the bottom to the bracket that is screwed with 2 screws to the bottom of the sash
Looks like a spring made of flat wire comes out of the bottom of the tube.
I got 19" tube for 36" tall window and 25" tube for 48" one.

Hello,

This old-style spiral balance hasn't been made in a long time. The good news is that you should be able to use the 5/8" diameter S500, along with the 17-012 mounting bracket that is sold separately. Look these products over and see what you think.
