Builders grade windows are usually non-tilt, but this looks like a tilt window spiral balance. Can you confirm? If so, I recommend our Series  900, which has a 3/8" diameter outer tube.

With no color tip, you will have to weigh your sash on a scale and get its precise weight. There is no other way to determine tip color.
