Installed Coil Balances working but not in all locations of the window

Question

I installed the 3 LB SERIES 140 QUICK-TILT, SINGLE Product Code: S140-3 for a bathroom window and am pleased with your delivery and overall results. I do note that the window will stay open when raised 1 inch and all the way up. However the window does not stay open halfway. Did I order the wrong weight? There was no labels on my window so I hand weighed and added a little to select the series. If I order another set at the next weight up will it solve the problem or should I look elsewhere in how the window works for a solution.

Again, so happy my condo association management team was able to point me to your site for the parts.

Thanks for listening.

I'm sorry to hear that our balance didn't work out for you. Can you tell me how much your original sash weighed? Can you also tell me what number was printed on the old stamp?
