These shoes are compatible with the 1/2" wide, Series 160 coil springs. To determine which spring you need, check the metal coils for any stamps. If there are non stamps, you'll need to divide the exact window weight by the total number of coils in the window. The compatible coil spring cover is part 15-150D.
