Double coil window balance

Hello

I think I have Simonton Windows

The photos are for the double coil balance

One side had the coil come out and get bent

Should I replace all the parts with the 15-087, 15-086, S180-5?

The coils has a 5z on it

Do I need to buy spreaders or can I cut the channel?

I just saw that the pivot post has 6221 on it and your previous posts say that is a Schuco window part.

So I believe I have Schuco double hung vinyl replacement windows and require a double coil window balance assembly

Thank youThank you

Thanks for posting. I agree, this looks like our 15-087 Coil Housing Pivot, which works with our 15-086 Housing. This system uses our Series 180 Coil Springs. I'm not sure if I'd trust the numbers stamped on the housing itself; your best bet would be to remove the housing from the jamb track so you can extract the coil springs to see what, if any, stamped numbers they have on them. If there are no stamped numbers, it would be best to weigh your window sash. You can then divide that sash weight in half to know how much weight support you need on both sides of the window. 

For removal of the coil system, jamb spreaders aren't necessary; see the video below for details.
