Help with coil balances

Quick Learner from IL
Hi, great website and support, thank you for the ability to submit a question about a part. I have Gorell Pro-Design 5100 Series windows, and the coil balance broke. When googling for Gorell, all sigs pointed to your website. Thank you for all your help! Pictures attached with the window and coils in question. Also, how do you remove them?

Hello! Thanks for reaching out to us. Looking at your photo, it looks like you have our 15-087 pivot carrier. This is designed to be compatible with our Series 180 coil spring. 

Your next step is to look over these parts to verify that their design and size matches your old hardware. You'll also need to remove the old spring to get its weight stamp. Note that I bring up the 15-087 pivot carrier only as a point of reference; assuming your old carrier is still in good condition, you can reuse that and just replace the spring by itself.

Hi, I could not find a number on the coil, but I found a number on the carrier, the number is PAT 5353548, I think this is it:

That definitely looks like our 15-087 to me. As long as the dimensions match up then our Series 180 should work perfectly fine for this application.

If there is no stamp printed on the old spring, then you will need to weigh your sash on a scale and divide that by the number of springs that support it; in your case, that'd be two.

So, for example, if your sash was 10 pounds, you'd need two 5 pound springs. If it was 8 pounds, you'd need two 4 pound springs. And so on.

Thanks Tom will do tonight

Tom - I weighed the window sash and the weight was 14lbs. So I need to purchase two Coil Housing Pivot (Product Code: 15-087) and two 7 lbs Series 180 Coil Balance (Product Code: S180-07)? Is that everything? Do the coils come pre-installed in the housing?
Do I need Tandem Coil Housing (Product Code: 15-086)?
Thanks! Tom

Yes, that's correct. For a 14 pound sash, using one 7 pound spring per side will be perfectly sufficient.

These parts don't come pre-assembled, so you will have to put them together as you install. There's also no need for the 15-086 tandem housing since you're only using one spring per side. You'd only want that if you had two springs per side.

Thanks Tom, I'll be ordering these shortly. Do I put your name somewhere on the order to indicate that you helped me?

Awesome, thank you! We really appreciate the business, it means a lot.

There's no need to put my name anywhere, but that's kind of you to offer. Just be sure to reach out again if you had any other hardware questions in the future.

Hi, I received everything, how can I assembly the coil housing?

To assemble this balance assembly, the spring and drum go inside one half of the 15-087 housing, then the two halves of that housing just snap together. Make sure that the spring is facing up before you snap it together, so that it can extend up to hook onto the mounting bracket.
