Coil window balances

Question

I think may be part a Series 160 because it is .5 inches wide and has the same type of connector tab that connects to the window slide block as my broken one. I can't find anything though that tells me what weight they are. I have some pictures and measurements. I'll probably need about 14 coils.

Thanks
Greg

Hello, Greg. It looks like you have our 15-111 pivot shoe, which does work with our Series 160 coil spring. There should be a stamp on the spring itself to let you know which Series 160 you need.
