3/8" Spiral Balance

Question

Hi - I need to replace the spiral balances with what I believe are 32" Series 400. The current balances do not have a colored tip. Is there a way to calculate the color needed when the window is not removable to weigh? The windows are 30 3/4" x 32 double pane aluminum GA windows. Thanks!

Looking at your picture, I would recommend our S400-32 spiral balance. However, just remeasure your tube just to be sure this is correct.
