Hello! The marking says "7GI". Is that 7 pounds on each side, total of 14 pound window? (I can weigh the window too.) The two coils came apart on both sides, so the window doesn't stay open.

This coil housing is most likely a match for the 15-087 Coil Housing Pivot. It is compatible with the Series 180 Coil Balance. Since yours are marked with a 7, you'll need the S180-07.

The 16-031 Mounting Bracket is used to anchor the coils to the window track.
