broken coil need new

Hello,

We don't have this exact style but we do have a similar set up with 1/2" thick coil springs. Please compare our 15-191 to yours to make sure all the dimensions match up. It is 1-1/4" wide and 1/2" thick.

The coil springs will be the Series 160. You would hook them together and then hook the bottom coil spring to the pivot shoe, instead of screwing them on like yours. You'll also want to weigh the window sash and divide the weight by the number of coils in your window to choose the correct strength option.

The coil spring housing would be our 15-150D.Thanks for posting!
