The one on the right is clearly broken, but I'm not sure which one to replace it with? I have no idea what type of windows we have , but the home is almost 13 years old. Any suggestions??

Thanks for posting. Please see our 15-180 pivot shoe and Series 190 coil spring. I believe you'll find these match quite well.

Thank you!! There are several options when selecting the coil spring. I'm not quite sure how to determine which number would be appropriate for my window. How do I decide on the right one?

There should be a number printed on your old spring that you can use as a reference.

I am searching high and low for a number stamped on my existing coil and the only one I can locate is an "8". They do not match the 4 digit numbers that I can select from.

With a stamp of "8," I would recommend our S190-840. Each of these springs can individually carry 8 pounds. Two working together (one on each side) should carry a sash weight of up to 16 pounds. You may want to weigh your sash on a scale to make sure that's right.
