Thanks for posting. I recommend weighing your sash to confirm what strength Series 190 you need. That is the most accurate and surefire way.

Great! Assuming you are only using two springs (one on each side), then the S190-640 would be a great choice.

Awesome, thank you for the order. For lubrication, we recommend a silicone spray.
