My replacement window stopped opening. I attached pics of the parts, not sure which measurements you need, one of the two window pieces is 26X27inches.

It just looks like the spring is broken. Look at our Series 180 coil spring, which is used for windows like yours. If you also want to replace the other parts, see our 15-087 shoe and 16-024 bracket.
