We purchased about 20 replacement vinyl windows from Gorell Enterprises in 1995. A few years ago the balances began failing. We currently need to replace at least five of them. I've attached a photo of a lower sash, hoping that you can identify the style for replacement. Please advise.
Thanks.

We believe your Gorell model window used our Series 180 coil spring. This fits inside a 15-087 coil housing shoe and 15-086 coil housing top, which I see in your photo. You'll need to remove your old springs to see what number is stamped on them. That will allow you to select the proper Series 180 option.
There is a formula you can use to determine what you have based on the size of your window, but it's not always reliable. In my experience it's a little off about half the time. If you don't have stamps on your springs, it's far easier to simply weigh your sash on a scale. You then divide that weight among the springs.
Let's use an example. Say you weigh your sash and it's 20 pounds exactly. Then you count your springs: two on each side, totaling 4 springs. You want each of those springs to carry 5 pounds, adding up to 20 pounds of support to match your sash weight. Therefore, you'd want to buy 4 of our S180-5 coil springs.
Does that make sense?
My pleasure! Let me know if you need anything else.
