Replacement coil balance

We've just had a coil balance make a loud "snap" noise and appear at the bottom of the window slide, once I opened the window. Is this coil balance something that would have broken and fallen down, or is it something that may have let go and may be able to be reset back in place?

Thanks in advance...

Hi, Bryan.

It looks like your coil spring may have broken and snapped which would explain the loud noise you heard. We can help but we would need to see an undamaged pivot shoe removed from the window in order to ID the compatible coil springs. Take a look at the videos we've related on this page and let us know if they help.

Hi Emily, thank you for your response and the videos. I do not have any manufacturer made cutout for removing the pivot shoe, so I will have to try and make one, as per your video. However, I've noted that my window does not have a "sash stop" or "window stop", so my cutout will remain visible, unless I can find some sort of "plug" or piece of trim that can snap in there. I'm sending a video of what that side of my window frame looks like, so you can see what I'm describing....

Thank you for the additional photo! It appears your pivot shoe is a match for our 15-215 which is used in the Series 140 coil balance assembly. To determine what coil weight option is needed, look for a code on the band of the coil spring. If there aren't any, weigh your sash on a scale and tell me its exact weight. I can calculate what you'll need from there.

Sorry for the long delay in my response, but I finally did have the opportunity to weigh the sash in question. It is 17 lbs in weight.

Hello! If your sash is 17 pounds then my recommendation is the S140-9. A pair of these assemblies will carry sashes weighing 17 through 18.99 pounds. Just note that they are sold separately.

Thanks, and how much would a single S140-9 cost? Do you ship to Canada? Any idea how much shipping may be?

You can see a detailed price breakdown on the store page linked to in my previous response. We do ship to Canada, but I unfortunately don't know how much shipping would be off the top of my head. I can tell you that the cost will be calculated for you automatically during the checkout process.
