Coil spring ID needed

A handy person from Maryland says:

Window balance experts,

I'm trying to identify the correct coil springs to replace the broken spring shown here in one of my photos. I've also taken pictures of the shoe and the attachment for the spring up top. There is no obvious identification of the window manufacturer, but the windows were installed when we built the house new in 2001, buy a neighborhood developer in southern Maryland. If pictures of the window would help I can send one of those too.

Thanks.

Jim

Thanks for posting. This appears to be an older version of our 15-180. Carefully review and compare the measurements below to confirm that these are the right fit. I am confident these are the correct replacement for your hardware.

These are compatible with the Series 190 coil balances. To confirm which coil balances you have, you'll need to confirm the stamp/marking from the metal coil.
