Series 152 Coil Balance Markings

A home owner from Phoenix, AZ says:
Hello,

I have style 152 coil balances (1/2" wide with tapered ends) in my windows. For a particular window where the springs have broken, the two springs are marked "D L" and "C". Could you tell me what weights these springs are?

I'm not sure. These kind of springs don't usually have letters stamped on them. The C might be our S152-3 and the DL might be our S152-4, but that's just a guess. I recommend weighing your sash. If I know the sash weight and how many coil springs are used in the window, I could recommend the appropriate part.
