Hello, thank you for posting!

The 15-180 pivot shoe is compatible with our Series 190 coil spring. Please let me know if you have any further questions.

The only number on the spring is 8. I assume that this is a 840 spring. let me know if this is a correct assumption. Best regards Joe

Hi Joe,

Yes, the S190-840 should be a good match for you, meaning the spring can hold 8 pounds. If there is one coil on each side of the window, the total weight of your window sash should be 16 pounds if you want to verify! Please let me know if you have any further questions.
