This is a ballance on a vinyl replacement window. The lock on the window has a MW on it but my local dealer says they are not Marvin Windows. The windows are 22 years old from when the house was built. It is from the left side of the sash when looking at the window from inside the house.

These old crossbow balances aren't made anymore, but you can replace them with our Series 795 Channel Balances. See the video below for details. |
