Any Locking Mechanism for a Casement Window in Partial Open Position

A home owner from Arlington, VA says:
I have a slim casement window for the bathroom. The glass window comes with two levers which you use to push the window outward & open.
I keep the window open for perhaps 10 degrees, the equivalent of 1 inch at the widest part (opposite the hinge location). It stays that way in warm weather. I keep it shut during winter.
What options do I have, when I keep the window partially open ? I would like to know both the hard-to-install ones, and, those that are easier-to-install but probably also easier to be tampered with. The purpose is to make it challenging for an intruder who tries to get in from outside through this bathroom window.
I have a screen placed on the bathroom side to keep bugs out.

Take a look at our 39-398 sash stop device, along with the video below. See if you could use this on your window to limit the opening. That said, I'm not sure if you can limit it to a 1" opening.
