Looking for a child proof locking mechanism to fit on a casement window that meets ASTM f2006 code for City of Los Angeles.

The windows are Pella Impervia Fiberglass.

Thank You,

Hi Gary. I wonder if something like our 39-398 or 39-398SS Sash Stops could do the trick. Watch the video below and see what you think.

I'm afraid I'm not familiar with that particular series, but these stops are compatible with most types of casement window. As long as there is room to install it I think there's a good chance that it will work.
