No color on top of spiral balance

A handy person from Indianapolis, Indiana says:
If there is no color on the tip of the spiral balance which balance do I order?
The length is 29" x 5/8" wide.

Thanks for writing in. Is this a tilt window? If so, see our S600-29 Tilt Window Spiral Balance. If there's no color tip, you'll need to weigh your window sash. You can then match that exact weight with one of the weight ranges listed alongside each color tip option on the product page.
