Window Coil Blalance

Question

Looking to replace old worn out window coil balances.
Our windows were installed in a new house in 2003. The manufacturer of the windows
was MWWindows who were later purchased by PLYGEM in 2004.
The coil itself is stamped with the number 7 on it.

Several of the windows had a serial number 112-607175 31 1/2 x 53 1/4"
112-607186 31 1/2 x 59 1/2"

Thanks for posting. Our 15-177 coil balance shoe should work well as a replacement. This shoe uses our Series 152 coil spring. For the stamped number "7" you provided, will correspond to our S152-7 coil springs. Make sure to review all parts to ensure these are compatible to what you have.
