Pivot bar for YKK vinyl Windows. Patent number 6378169. I need a higher resistance because 6R does not hold the window in the open position. I need 9R. Do you have this in stock? Thank you.

Hello! This part is known as a window coil balance. Specifically, yours looks like our Series 140 balance, though I would like you to confirm the weight of the sash before we recommend the S140-9. It is possible for a balance to be too strong. Let me know!
6 lb Series 140 Quick-Tilt, Single
