How wide is your coil? If the 15-150D was too deep, the 15-204 might work. It is used with a 3/8" thick coil, whereas the 15-150D is used with 1/2" thick coils. If you provide the thickness of your coil, we can identify it.

Trouble with the 15-150D is it breaks the latch when closing window.
Does the 15-204 have 2 screw holes?
Mine is 4 inches long.
I think the 204 might work spring is 3/8 thick
Can you send me 4

Some window manufacturers made their own exclusive coil spring covers when the generic type wouldn't work. Before you order the 15-204, check the depth of your coil springs. If the spring is 3/8", then the 15-204 should fit fine. If it is 1/2", though, then we will need to think of something else.
