coil spring

Question

I know I need to order the 15-180 and the series 190 coil. My window weighs 20 pounds. Can you please tell me all the parts that I need to replace the entire mechanism for my window. I know I need to order 2 of each to replace both sides. What coil, do I need the balance bushing, the clip and what screws. Thank you.

Hello,

You only need to replace the parts that are broken but I've related all of the parts from the related items section of the S190 product page for you to review. I would also recommend using two of the S190-540 coils on each side of the window to support a 20-pound sash. Thank you.
