Which coil balance assembly do I need?

Question

Hello!
I haven't dealt with windows before, but I am pretty sure I need a coil balance shoe, a double support detention clip, a balance bushing, and a coil balance spring. I would need one of each for the left side and one one of each for the right side. The sash weighs 7.4 lbs. I am not sure if I would need the S-140-7 or the S-140-8 balance system. Does all of that come with the single coil Series 140 Quick Tilt Force Balance System or would I have to get each component separately?

Thank you!

Hey there!

Unfortunately, the coil balance assembly you have is not

Your coil balance shoe appears to be our 15-180. Take a look at the dimensions on the diagrams, shown below, to confirm that this is the replacement you'll need:

Also, given that you have the double support detent clip, are you certain of the sashes weight? The double support clip suggests that this coil balance assembly may carry more weight than the 7.4lbs.
