Series 160___________________________ matches what you have. It looks like your old shoe is our 15-111, which is compatible with our Series 160 spring. You only need to replace what's broken, so if the springs are the only things broken on your window then you just need to buy the Series 160. You'll need the stamp on the old spring to confirm the best option.

So I had to check every spring in the place before I found one that wasn't rubbed off. The spring was labeled '#6.5 35" PATS 5232203'. So does this mean I should get a 160 spring or a 165? And how do I know the apropriate weight amount for the spring?

The stamp does not indicate Series, it indicates how much weight it supports. Your spring carries 6.5 pounds.

The spring commonly used with the 15-111 shoe is our Series 160, which is 1/2" wide. The Series 165 is 3/8" wide. That's the determining factor. Yours should be 1/2" wide.

If your stamp reads 6.5, you'd want our S160-6.
