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. |
