Broken coil balances
Hey Jeff. I believe this is a 15-087 Coil Balance Shoe and 15-086 Housing. This system uses our Series 180 Coil Balances. To know what spring weights to select, you'll need to remove the assembly and look for stamps on the coils themselves. if there are none or you're unsure, give me the exact weight of the window sash, and I can work it out for you.
I hope that information helps. The sash is part of the upper or outer section of the window and I was wondering if this would be difficult to replace once we get the right parts.
Hello! Bob isn't here today, but I can help you out from here.
So, since your sash is 17 pounds and you have 4 springs per side, that makes me think our 4 pound Series 180 option is your best choice. That falls a little short of 17 pounds but only by a pound. I don't think you'll notice the difference, to be honest.
Alternatively, you could use one 5 pounds and one 4 pound spring on each side, which totals 18 pounds of support. Again, I don't think an extra pound off either way will do any harm. It's ultimately up to you!
As for how difficult it is to replace, I won't lie to you. Coil balances can be a headache. You'll have to squeeze these out of a small cutout in the jamb, then squeeze the new assembly in while it's all mostly put together. If you can afford to make the cutout a little longer, you may want to consider it just to make your life a little easier. I use a utility knife.
Thanks,
Jeff
