3606 Window sash balance

Sure thing! I'm very confident we have a balance that can work for you. In your case, I was able to narrow it down to two choices: either our S380-37 or S385-37. The only difference between them is the depth of the bottom nylon fitting. 

To get that, stand your balance straight up as it looks while installed. Then pretend the bottom fitting is a shoe or foot. Measure it from heel to toe and compare it to the two products I suggested.

One last note. Your stamp is also a little peculiar and I recommend weighing your sash on a scale to determine if one of our stamp options can work. We have a chart on each balance's store page t hat tells you how much weight each stamp supports. If your sash exceeds the weights given, let me know and we can try to come up with a solution.

Thank you for your kind words. We are happy to be able to help great customers, such as yourself. If any other questions come up, we are always here.
