39-077 with a screen?

With this window adjuster, it is difficult to attach it to a permanent type of window screen. You would have to install the screw with some type of clips that can be moved out of the way or some type of hinge on the screen so it can swing out of the way every time the window needs to be pushed open.

You can get the 39-077 to work with a little improvising not to interfere with the screen. One way would be to install the 39-077 on the sill between the glass sash and the screen. What you would do is open your screen panel (putting it on hinges is a good way to do this), open the window then close your screen. I have done it this way, it seems to be the easiest way. Just make sure you have room on the sill between the glass and screen panel. You can always move the screen inward to allow more space on the sill if you don't have the room between them. There are many ways to do this, this is just my suggestion. You might want to get a carpenter to help you with this.
