vinyl window ballance

Hello,

Your photos resemble the 15-180 balance shoe, which is compatible with the S190 coil springs. Take a look at the product's specifications and compare them to undamaged parts to confirm. Thanks for posting! 

That would actually be too strong for a 26-pound sash. I would recommend using one S190-640 and one S190-740 on each side. 

I'm sorry to hear that you're having trouble. I see that you only purchased one of each coil, so I'm assuming that you might have installed one coil on each side of the window. What I meant was that you would need to use the S190-640 and S190-740 on each side of the window, meaning that you would need a total of four coils. 

I recommended these because you would have 13 pounds of support on each side of the window, which would support a total of 26 pounds based on your sash weight. Hopefully this clears up the confusion. 

Hey there! Casey isn't here today, but I can help you from here.

Based on the weight of your sash at 26 pounds, then her original assessment was accurate; you need a 6 and 7 pound spring on each side of the window. That gives you 13 pounds per side, for 26 pounds total. We sell the 15-181 double spring clip and 15-182 bushing, in case you need an extra one.

If your original springs are marked with 832, that means they only hold 8 pounds each. With only one on each side, that's only 16 pounds of support. That's very weak for such a heavy window. You may want to triple check the sash weight just to be sure.
