Coil Balance

I need to replace these parts with new ones. The sash weighs 30lbs. I have changed similar parts for sashs weighing less then 30lbs but did not find a coil balance that supports 15lbs.

Hello,

I see that we have recommended you follow the conversion video below in the past. For a 30-pound sash, I would recommend using the S159-10 and S159-4 on each side of the window. You will need to stack the coils before installing them in the window. Thank you!
