My window balance fell from the window pane and now needs to be replaced. The the spring is detached from the pulley as shown in the attached 3 pictures. I think that the maker of my window is "nami" as shown in the 4th picture (the window's label). Can you identify the balance so i can order its replacement?
As a follow-up, added pictures of numbers stamped on my balance and broken plastic fitting on end with pulley. The width of channel holding the spring is 9/16 in.
