Good Morning, We are getting ready to install the 20-013 on our double hung windows. Should we install ONE lock per window - or two - one on each side?
Thank you.
Thank you.

It is recommended that you install two of these vent locks per sash. That would be one 20-013 Wood Window Vent Lock Set per sash.

OK....this means that the top sash cannot be pushed down either when the ball is set to lock...right? I have double hung wood windows.
