Window won't go all the way down

Question

Decided to replace block and channel from Swisco because window wouldn't close all the way without a lot of force - this caused the screws in the lock lift up and become dislodged since it was the only thing preventing the window from coming up. Ordered the new part (2650) and the same problem is happening. What am I missing?

Hello there!

Thanks for reaching out to us. It sounds like the 2650 strength option you selected is too strong for your window. To confirm, you will need to weigh the window sash on a scale. Let us know the precise weight and we can work from there.
