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.
