I have a failed coil balancer on a window. The weather stripping came off and got in the track. The window was forced open and broke the balancer. By looking at the coil I guess it is a series 180 but that is a guess. The text on the frame of a similar window is: WSIGCC(R)/IGMA(R) L15071900013705 55548 4-6.
The coil seems to be fine but the support and mounting clip are broken. I assume again they are single inverted supports.

Yes, this assembly uses the Series 180 coil balance. However, since the housing is broken I suggest taking a look at the S220-16 Roller-Tilt assembly. Like yours this has (2) 8lb coils. It will come fully assembled and ready to install.
If you are only looking to replace the top housing, please see the 15-086 Tandem Coil Housing.
The specifications, for all of the recommended hardware, can be found on the website.
I'm sorry to say we do not have a replacement for the kerf mounted wool pile seal you have. Apologies that we could not be of more help with this part of the repair.
